VM with poor performance (CPU)?

I have a virtual computer that runs 'wrong'... checked esxtop for all relieved symptom but found nothing.

Average usage of the CPU to 2 vCPUs is about 50% and more...

Checked with performance, the swap file usage monitor, but the file is not used, use of memory 2 GB to 3 GB... of ideas?

PrintScreen of my VM in esxtop is in attachment (the name of the virtual machine is not visible)

The post said two vcpus.

I might try the virtual machine with one vcpu and see if this improves performance.

If you find this or any other information useful or appropriate, please consider giving points.

  • Inspiron Intel Wireless N 7260 with POOR performance

    The laptop was purchased 8/2014.  I'm having problems with my WIFI connection and our cable service provider out today.  They have isolated the problem to the laptop.  They proved this by running tests of speed on different devices.  This laptop was the only device that produces slow download speeds<6 mbps="" while="" the="" other="" devices="" are="" running="" anywhere="" from="" 50="" mbps="" to="" as="" high="" as="" 90="" mbps. ="" if="" i="" connect="" this="" laptop="" via="" ethernet="" it="" runs="" in="" the="" 90="" mbps="">

    WIFI on this device is an Intel Wireless N 7260 and the 16.6.0.8 driver version runs at 2.4 GHz only.

    Does anyone know if this is faulty (it passes all the tests) or is it something that needs to be upgraded already?  Y at - it an upgrade?

    jjdeadhead,

    Did you recently install/reinstall/upgrade the operating system?

    Have you tried the drivers from the Dell website? Go to drivers and downloads , enter your service tag, select your operating system, network, download the drivers and save them to your desktop.

    Do a system restore point.

    Go to Device Manager, network cards, click with the right button on the Intel® Dual Band Wireless-N 7260, left, click on uninstall. Tell him to remove the software and drivers. Then, restart your computer. When you connect, the new hardware wizard will try to install the drivers. Install the drivers that you saved on your desktop.

    Try these tweaks...

    Start, Control Panel, Manager of devices. Click Network and then right click on your network adapter, on the left, click on properties, power management. Uncheck the allow the computer to turn off this device to save power.

    Go to the options power and changed the wireless adapter setting, adjustment of maximum power for maximum performance.

  • Help setting up a SQL query with poor performance

    Hi all

    Database version: 10.2.0.5

    I'm working on a new report to view the top users by the number of calls. The table is truncated and filled again every month with records for the previous month; It contains approximately 400 000 records.

    I created a view with the columns needed for the report; also, the two functions of view calls to determine if a phone number is assigned to multiple staffs or several departments.

    It's full again table every month:

    These are the functions to determine if a phone number is assigned to multiple staffs or departments:

    FUNCTION GET_EMPLOYEE_NAME (P_FROM_FULL_TELEPHONE IN VARCHAR2)
RETURN VARCHAR2
AS
  L_NAME EMPLOYEES.NAME%TYPE;
BEGIN
  SELECT NAME
  INTO L_NAME
  FROM EMPLOYEES
  WHERE WORK_PHONE_1_FORMAT = P_FROM_FULL_TELEPHONE;
  
  RETURN L_NAME;
EXCEPTION
  WHEN TOO_MANY_ROWS THEN
    L_NAME := 'Multiple Employees';
    RETURN L_NAME;
  WHEN NO_DATA_FOUND THEN
    L_NAME := 'No Employee Assigned';
    RETURN L_NAME;
  WHEN OTHERS THEN
    NULL;
END;


    FUNCTION GET_DEPARTMENT_NAME (P_FROM_FULL_TELEPHONE IN VARCHAR2)
RETURN VARCHAR2
AS
  L_DEPT_DESCR EMPLOYEES.DEPT_DESCR%TYPE;
BEGIN
  SELECT DEPT_DESCR
  INTO L_DEPT_DESCR
  FROM EMPLOYEES
  WHERE WORK_PHONE_1_FORMAT = P_FROM_FULL_TELEPHONE;
  
  RETURN L_DEPT_DESCR;
EXCEPTION
  WHEN TOO_MANY_ROWS THEN

  WHEN NO_DATA_FOUND THEN
    L_DEPT_DESCR := 'No Department Assigned';
    RETURN L_DEPT_DESCR;
  WHEN OTHERS THEN
    NULL;
END;

    This is the point of view that I'll use in the report:

    It's to you if you are satisfied or interested in improvements (if possible).

    If so the first thing I would like if you had your refreshed perspective as advised. According to expected area_code table cardinalities I doubt.

    So, if not cool off with dbms_stats.gather_table_stats on two tables, area_codes and MONTHLY_BILLING_DETAILS.

    Bottlenecks are now obviously the full table of MONTHLY_BILLING_DETAILS as well as the ANTI of LOOPS IMBRIQUEES scan.

    At the moment I don't think that an index of MONTHLY_BILLING_DETAILS will help a lot, because most of the lines will pass filter predicates, and because we need some columns in it, I have now I there will be gain a full index scan.

    I was surprissed that the optimizer pushes the substr <> predicates to both tables.

    So depending on your data, you might try

    1 make a factory of subquery select the two MONTHLY_BILLING_DETAILS columns that all directly apply predicates of membership and use it directly in the join instead of the table.

    or

    2. If all subtr to so are part of the table area_code choose in it using a subquery (or inline view) plant excluding these values.

    Both are attempts to get rid of the substr excluding as filters of join predicates.

    In fact, I was expecting a hash join anti as shown in the plan to explain instead of the nested loops anti, I expect to be more effective in this case.

    Perhaps with correct cardinalities the optimizier would understand himself.

    Just to test it, you can try the use_hash hint in the join:

    Select / * + USE_HASH (MBD, one) * /.

    ..

    OF MONTHLY_BILLING_DETAILS MBD,.

    NYNJ_METRO_AREA_CODES one

    (It's a good habit anyway usually use aliases and precede the names of columns. In the, it is easier to read queries are only trivial).

  • Poor performance of Firefox after you apply the latest Microsoft Updates (Win 7 x 64); all solutions?

    Recently, I updated to Firefox 27 and noticed really horrible performance (Manager tasks indicates FF connecting a carrot, frequent "Firefox is not responding messages", even strikes in late development in the URL bar). It's on an Ideapad s205 (AMD E450 APU, Win 7 x 64, 8 GB RAM, SSD) who has always had pretty decent web browsing performance for a low end machine.

    At first, I blamed FF because poor performance coincided with the update to version 27, but now I think that the first cause to be a recent Microsoft Update. The reason is that my wife has a laptop with a same low-end APU (APU C60, hard drive 5400 RPM, 4 GB of RAM, Win 7 x 64), and she was getting much better performance with FF27 until I applied a backlog of some 90 + updates. Now she suffers from the same poor performance I am and she is pretty p * ssed at home.

    Interestingly, I have two WIn 7 x 64 Intel computers to office who have 27 FF and are fully patched, and performance are very good. Maybe this problem is specific to AMD APU.

    Any thoughts? I tried to turn off the backend Azure with some comments in this forum, but makes little or no difference.

    Thank you!

    Success! 32 FF seems to have solved my problems of performance. Thank you!

  • HP Mini 110-3530NR extremely poor performance on the Internet

    My HP Mini 110-3530NR Netbook has very poor performance on the Internet.  I use Windows 7 Starter.

    Say hello to new coppens1.  I apologize for the delay in my responses.  I have not received the normal e-mail notifications.

    When I had to go to msconfig earlier in our interactions you make sure that the Synaptics driver load with Windows?  Follow these steps to check.

    1. Click Start, type "msconfig" and press ENTER.
    2. Go to the Services tab and search for "HP Software Framework".  This should load with Windows for a lot of the HP software to work properly.
    3. Then go to the Startup tab and make sure that anything it either by "Synaptic" is loaded with Windows.
    4. Save your changes and exit msconfig.
    5. Then go to your touchpad settings and, even once, make sure that the settings are correct.
    6. Finally, restart the machine and make sure it works properly.

    I totally understand if you want to open a new thread as this covered a few topics!  Just make sure to send me a private message with the link so that I can make sure to help you here.

    I wish you a beautiful day JC!

  • SG300 switches have poor performance in layer 3?

    We have several switches SG300 Serices. We use them to route traffic to VLAN remote offices, the Internet connections and wireless access Points.

    In a remote office, we have a SG300-10 facility to route the HQ network and the remote office subnet. The SG300 is connected to the seat through fiber and contains several VLAN Tag. If I speed, tests on the fiber of the entrants Netwotk tag link I get decent performance, 80Mbs. If I switch to a networtk who is not priginating of the central administration and road SG300-10 package, I get poor performance. 15 - 20Mbs.

    I have Fireded until a new FW SG300 - 28 p v1.2.7.76. Added a HQ VLAN 101 and VLAN new, 1025. Mapped some Tagged and not marked for each ports.  Switch has been connected to the network of HQ as untagged VLAN 101.  I put a laptop on a unmarked port VLAN 101. Ran some tests, cam is back with 750-850Mbs. great.  Put the same computer laptop on a Port of 101 tag, set the NETWORK card for tag VLAN 101, same test, same speed, 750-850Mbs.

    I configured then laptop for tag VLAN 1025. Connected to the port 1025 VLAN scored. Done speed tests, the results were 15-20Mbs!

    Then I configured laptop for Untagged VLAN 1025. Connected to unagged port 1025 VLAN. Done speed tests, the results were 15-20Mbs!

    It was only the laptop and connect to the net on the SG300 - 28 p P.C. Why this device's performance is so poor when he needs to route?

    Other switches have v1.0.0.27 FW or FW v1.1.2.0. They have similar speed problems. All configured for layer 3.

    Thank you!

    How are customer gateways and server configured?

    The default gateway for connecting devices should probably be that of the IVS, they are directly connected to. So if you have a server connecting to a SVI 192.168.1.100 then the gateway server should be 192.168.1.100, not a router upstream. Who can create a loop of road if the return circulation.

  • VPN poor Performance - Cisco RV220W and routers WRVS4400N

    Hello

    To one of our customer IPSec VPN is established between Cisco RV 220W and routers of Cisco WRVS4400N.

    From the day that VPN has been implemented, the performance was poor. Frequent disconnections sessions live to the VPN nodes and very low transfer rate was alarming to users.

    The servers in A location and users to the site B gets authenticated at the server DC level in A location

    Applications of Terminal Server remote as Quickbooks, QQ Evolution, attendance RX serve also the location has by users to the location B

    The login is your time and all applications are extremely slow.

    I tried to copy files between share data between two locations and the results are as follows

    Location A to location B-> 130 Kbps 140 Kbps

    Location location B A-> 150 Kbps to 160 Kbps

    What can be the problem for these poor performance VPN?

    -Change the encryption for the least secure OF THE /MD5 would have a significant impact because it can reduce the overload on the routers?

    -Even if both routers are routers SMB, it has really good VPN flow according to the data sheets. I couldn't find VPN flow mentioned in the WRVS4400N data sheet. One of the sons of CSC, I also noticed the VPN of WRVS4400N flow seemed really low as only about 1.6Mbps. (https://supportforums.cisco.com/thread/2107881)  Whereas RV220W router has VPN 90Mbps flow, according to the datasheet.

    So, what can be the cause of the problem and what can be fixes possible?

    Help, please!

    ANUP sisi

    Beginner to router Cisco VPN, please help

    RVS4000 was designed to work in a small office. It supports 5 VPN tunnels with a maxium of 2 Mbps flow measured in a laboratory environment. It has a processor that has a motor integrated IPS, who would deliver 20 Mbps LAN - WAN throughput when IPS is enabled.

    RV220W has been designed to operate in a slightly larger office with 25 IPsec VPN tunnels. It has a processor that has a built-in cryptographic engine able to deliver throughput 90 Mbps of IPsec. RV220W also supports 5 SSL VPN tunnels that can be used by employees and business partners for remote access.

  • What is the problem with my performance?

    Hi, I have problems with the performance of my computer... I have 4 GB of RAM and AMD Athlon 64 X 2 Dual Core 4200 + CPU GeForce GTX 460 graphics card. I have performance issues when running from Brothers in Arms: * the of Highway.I asked a lot of people, and they suggested that my CPU is not very good, but when I asked other online players they told me that they have Intel 3 GHz, 3.3 Ghz Intel and similar and they have a good performance. I don't see how they can be better than me, when I have a better processor... I don't know much about processors, but I've heard of Dual Core and Core 2 Duo CPUs.Some people say that the Core 2 Duo have better performance in games, but I don't really know if it's true because, as I know, is Intel Core 2 Duo and AMD Dual Core is, and it's just a different name for the same thing just different manufacturer. My CPU cores working separate from each other as 2 different processors (in this case I would 2.1GHz for the game and the other 2.1GHz for something else) or they work together by offsetting each other and I have to install drivers or something so that they begin to work correctly (in this case, I would at 4.2 GHz for the game)? Earlier, I got AMD Athlon 5200 + CPU (when I ordered it I asked tri Core 2 Duo and not Dual Core because of the stories I mentioned above) and was running Win XP and I had no problem in running the game, but that CPU broken and since I hit motherboard AM2 and AM2 CPU foot isn't in production anymore I got degrade up to 4200 + and I now run Win 7 Ultimate.I know that this one is lower, but I think that he should not have so much difference in performance for this game.

    There is a free download "Game Booster" application that you can try. It can free some resources to help your performance of some. I used it on my previous PC, but it makes no difference on this configuration. They shared opinions on it, but I liked it when I got it.

    http://Lifehacker.com/5641772/game-booster-optimizes-your-PC-for-gaming-in-one-click

    I just checked again and their latest version is 3.2
    Good luck with the game.

  • Poor performance Alienware 13

    Hello, I have recently updated my Asus G55VW to 13 Alienware and he's surprisingly poor performance in some games from my old laptop. As far as I know that I put everything to max performance but it is still low in some areas.

    Old sheet

    Intel i7 @ 2.5 GHz to 3.4 GHz

    NVIDIA geforce 660 m

    8 GB ram

    Alienware 13

    Processor Intel i5 1.7 GHz to 2.7 GHz

    NVIDIA geforce 860 m

    8 GB ram

    So far, Borderlands 2 runs poor while others like Warframe can operate at max settings no problem.  Other games like naruto shippuden ultimate ninja storm 3 full bursting cannot run because it selects only the integrated graphics card and I can not change... Right now, I think that the graphics card integrated into the issue and if there is a way to disable it, which could make things much better. Not to mention that any help to increase performance would be greatly appreciated.

    JLM264

    Alienware 13

    Processor Intel i5 1.7 GHz to 2.7 GHz

    You have a 1.7 GHZ dual core CPU... Borderlands 2 recommends the use of 2.4 GHZ quad core CPU

    Your "old" laptop ASUS who had a 2.3 GHZ quad core CPU meets this requirement more than your new machine

    Warframe works very well, because any CPU dual core is sufficient and that's what you have

  • disc Flash of poor performance

    Hello
    When I run $cellcli EI list physical disk, some of the Flash drive is showing a poor performance.


    alprod1st09: FLASH_5_0 1116M08EUW poor performance
    alprod1st09: there is no such thing as FLASH_5_1 1116M08EV9
    alprod1st09: FLASH_5_2 1116M08EVA poor performance
    alprod1st09: FLASH_5_3 1116M08EVC poor performance

    is it requires to call oracle for the replacement of flash drive... it is very critical?
    Kind regards

    One of your flash cards shows also absent I would suggest contact you oracle for a glance. You are on the last cell server software? There used to be a problem that caused problems with the pci riser cards. It is fixed in the latest software drivers.

  • Android apps have poor performance

    I have several applications created for Android and all my folios seem poor performance on android devices. It takes a long time for any article to focus on the text (all sheets are built using PDF), and there is a significant for interactivity in a Folio delay, if it does not crash the app entirely. Has anyone else had problems with Android apps? I have not read a lot of useful information on them.

    All my applications are built for android with the dimensions of 2048 x 1536 to make them readable on the Nexus-10. All applications have been rebuilt with v27 and PDFS.

    I'd appreciate comments you can give.

    Thank you

    One thing that can help with the Active Viewer is to design to a smaller size (1024 x 768, for example), use a PDF object and the viewer intensify folios to fit larger screens. Put scale up to adjustment is supported in our 28 Viewer version of AIR and it makes a big difference in performance while maintaining the reasonable quality of the assets.

  • Distributed replication of file system between servers with different performances

    If the published file system replication is set between servers with different performances. What will happen with the fastest server performance? The performance will shrink to match the performance of the server in the slower string?

    This issue is beyond the scope of this site and must be placed on Technet or MSDN

    Hello

    Make sure you have Superfetch and ReadyBoost running services and then try to speed up the startup using my guide [1]. This causes the prefetcher in Windows Vista. This increase startup performance a lot. All other tweaking tools are useless. Use this method only with this Toolkit from Microsoft.

    If it is not to speed up the startup process, follow my guide [2] to start and stop monitoring , compress the boot_BASE + CSWITCH + DRIVERS + POWER_1.etl andshutdown_BASE + CSWITCH + DRIVERS + POWER_1.etl like RAR or 7z and transfer it to your Skydrive [3] and post the link here.

    I take a look at the trace, maybe I see what's wrong with your Windows.

    Whenever I start my computer, I get the message: "this file doesn't have a program associated with to perform this action...". "for my external drives.  I use these daily backup USB drives. It seems that the backup will run, if I acknowledge this message by clicking OK. If this is not the case - it won't. Why is that happening and how can I solve this problem?

    You can repair the associations used to readers.  One of my fellow MVPS, Shawn (no relationship lol) has default binding settings in his site here:

    http://www.SevenForums.com/tutorials/19449-default-file-type-associations-restore.html

    Just scroll down to find the link of 'reader', click it, and launches the link.  You can do the same thing with "folder" and "directory" to be thorough.
