VM CPU speed limit - why?

• vSphere virtual integrated cpu speed limit?

  Hello

  I have a group of four vSphere 4.0u1 guests with many free resources (4-core nehalem 2.27 GHz + 32 GB RAM for each host). There is a virtual machine (linux Debian 5, 64-bit) with one vCPU. Though this VM would have more speed CPU (trigger alerts on the CPU usage), it becomes ever more than 2 GHz. In the resource pool, I tried to add several actions (up to 8000), but without success

  Is there a speed limit of vCPU in vSphere so that the computer only vay to increace pover of VM is to add an another vCPU? Or am I missing something basic, where can I put the maximum vCPU for all my virtual machines? I think vCPU shloud be scalable in DURATION up to 4x2.27GHz less what console service needs, while the other usingVMs of lesscpu must be migrated to other hosts by the Drs Is is it true or not?

  Thanks in advance,

  David

  Hello

  You'll never be more than the power of one heart for each vCpu. At any time, each vCpu is attached to a physical core. The ESX Planner do not aggregate the power of multiple processors to "emulate" a super processor.

  In your configuration, will have no more than 2.27 GHz each vCpu.

• Speed limit of network in the workstation?

  Do you know if there is no speed limit of network between the virtual machines running on the same workstation to Vmware? I think remember something about say 1 Gbps as maximum, but if virtual machines can provide throughput more - it will go by?

  Do you use bridged or one of the networks vmnet1 hostonly or 8

  hostonly networks are limited only by the host CPU resources

  But anyway - Gbit network is much faster than anything that can manage virtual disks

• Host Link link Guest speed speed limit

  Hello..

  It is a Question: is somehow the link speed of the host not to limit the speed of the link of a guest (VM) access the HOST?

  Example:

  What happens if we have a host that is equipped with a 100 Mbit NETWORK card and a guest who has a virtual 1 GB card NIC (Intel Pro 1000 thingy). OF COURSE the guest CANNOT reach the external network (Physics) with the speed of 1 GB or vice versa since its limited through the physical NETWORK adapter of the host...

  BUT... The Question now is... WHAT the maximum performance of such a guest if we want fair access network-HOST Services itself? It is a local connection, I guess. What speed can be achieved here?

  Background:

  I have here a host FAT on Ethernet 100Mbit, 16Gig RAM, 2 x Intel XEON CPUs, Debian 5.0.1 and VMWARE 2.0.1 4core. My guest inside is also Debian 5.0.1 with a 100mbit NETWORK card PCnet32 virtual thingy. My host can read data from local raid with about 120 MB/s (mega bytes/s). My guest (using iSCSI to enter the Volumes on the host and so using the internal virtual network) can read about 11.2 MB/s of the host Diskdrives.  It made me courious, since ~11.2MB/s is on a 100mbit NIC maximum flow. But it is a BIG difference on performance. BTW: the same client can access data files of local virtual disk of GIS (vmdk) by AT LEAST 120 MB/s (local caching disabled). So, where is the limit and the bottleneck?

  Any ideas/suggestions?

  And now you tell me... that the Networking Performance between guest and host VMWARE here is this effect limited to 100 Mbps, because I don't meet with the host NIC (which takes place in)

  100 Mbit)?

  Yes.

  But COMMENTS <>network HOST my NIC speed would not be limited if I'd put the guest in a virtual network "HOST ONLY"?

  Yes.

  If Yes... WOW! But... what would look like if you have Clients who want to access the Guest VM as a server files to a configuration/solution? you will need some sort of routing/bridging again.

  N °

  Oh... would be 2 NICs in this guest so be a good solution? like: < USER-BRIDGED-LAN >--< GUESTVM > [NIC2]-< HOSTONLYNETWORK >

  Yes.

  If the GUEST VM by wire-speed, users can access and GUESTVM access HOST of Services at the speed of the cpu. Is this correct?

  I didn't say CPU speed, I said, it depends on the speed of the CPU. But in general, Yes.

• Satellite Pro A300: XP - Internet HSDPA speed limit - only 1 MB

  Hello

  I am user of 2 different models of Toshiba Satellite Pro A300-1NT.
  I use XP Professional extracted from the original XP Recovery disk.

  When it is connected to internet provider GSM using ExpresCard HSDPA modem or HSDPA USB modem I get 1 MB speed limit control on speedtest websites (ie: speedtest.pl) and internet usage is relatively slow when comparing other computers.

  When Windows Vista was installed on the model of the A300 speed was greater than 5 MB.

  I already checked, I'm in the range of UMTS and speed on other computers (Toshiba Tecra with WinXP Pro, Toshiba A100) and M70 with Win XP Home with the same modem (Huawei) has no such speed limit

  What might be the case and the solution?

  Hello

  Have you checked the WLan performance using different WiFi standards?
  You can change the Wlan standards in Device Manager-> card Wlan-> properties-> Advanced tab.

  Check the settings there.
  I recommend using a WiFi standard 802. 11 G for example instead of B/G

  In addition, you should check if you can update the WLan driver and if the BIOS is updated.

• Is there a speed limit on the ethernet cards?

  Hey guys do you have an idea who is at - it a speed limit on the Ethernet cards, because I can use the P2P so fast that, after awhile, my internet connection is stopped as, I can't do anything unless I unplug, wait a while and connect again. Don't you think that it is a hardware or software problem?
  By the way: my Ethernet card is Marvell Yukon 88E8036 PCI-E Fast Ethernet Controller.
  I need your help. Thank you.

  Hello

  In my opinion, if you have some problems with the internet connection the reason should not be any kind of speed limit but also other different reasons.

  In your ad, you're not mentioned that you do exactly. You write e-mails or do the download of two different movies and many mp3 files?

  As far as I know if you do the full download the connection can be slowed or even stopped by FAI. Is your cable may be defective. The LAN cable has 8 lines and if one line is faulty speed will fall automatically.

  I also recommend you use a malware scanner and check the unit.

  Good bye

• SPEED LIMIT OF DOUBLE CLICK KEY

  I have a HP Probook4540s runing Windows 7 Professional. Last night, he started a speed limit on double substitution in a screen or program any key. Whenever I have a double character like "ee" or "oo" or same double line spacing or BACKSPACE or delete, once I hit key desired, I have to wait a second or 2 before I hit him again so he could register.  I don't know that there is a setting somewhere where I need to check or uncheck a box, but I have no idea where he might be. I've looked everywhere I can think of. It is not specific to a certain program, it happens in all programs, all screens.

  Hello

  Check the following points.

  Open windows control panel, open ease of access Center and click on the link "make the keyboard easier to use.  If there is a check mark in the box beside "Turn Sticky Keys" or "Turn on filter keys", delete them and then click on apply to save the changes to see if that solves the problem.

  Kind regards

• Help! Why my amd turion64 X 2 TL60 2 ghz CPU speed test REAL slow. ALL THE WORLD?

  HP DV6810US w / 2 G DDR2667 & above mentioned purchased "refurbished" CPU w / guaranteed off Ebay.  tested on cpuspeedtest cpuspeedpro & Assistant to run @ 800 mhz.  That's only 1 core?  Despite this - a little slo' Vista device mgr shows 2 TL60 listed & working properly.  How will I know if I really got what I paid?  & If so how to test above?  other TL60 on these speed sites are synchronizing @2 = 3 ghz.  WTF?

  someone please = will be appreciated...

  To relax. Computer laptop CPU using a speedstepping program slowing down mode sleep to save energy. Before you run any kind of test excites the power profile always overrride the processor driver program. Otherwise, it tests its slow speed by default about 800 MHz.

• Confusion of CPU speed!

  My speed cpu database is written 997,7 mhz cpu - z, it should be for a right t5450 1.66 ghz?

  May be the result of the lower clock speed to save energy. Your CPU will dynamically change its clock speed depending on its load. You can watch the gear shift to clock using Rightmark CPU Clock Utility found here: http://cpu.rightmark.org/download.shtml, direct download here: http://cpu.rightmark.org/download/rmclock_235_bin.exe

  Go to the monitor option and look at the clock up and down between 1 GHz at 1.66 Ghz.

  Or, it is possible that you are in power saving mode. I think that automatically limits the upper limit of the clock speed to a certain value. Try to switch to high-performance mode.

• Upgrading my cpu speed zip files in Windows 7

  I currently have an i3-2100 (Socket 1155).  I compress TIFF files (137 MB each) in records of 15 or more.  It takes forever.  I checked my use of RAM and it runs around 37% while the zip compression and listen to trance music streaming from Youtube at the same time (from 4 MB of RAM installed) to get more RAM doesn't seem to be the solution.

  Would a processor "more powerful" speed things, hopefully much (stay with Socket 1155)?  Or is program of internal compression of W7 (what I want to continue to use it as people who receive my files zipped using Windows Explorer to decompress files) just by nature dog slow and isn't really dependent on cpu?  You know, it is what it is.

  So far no response.  If anyone has a suggestion for another forum post this question please let me know.

  Asked me to come back and "finish my thread.  Well, no answers here, so I asked on a photography forum and it has been suggested, I have try 7 - Zip.  This free program, in fact, compressed files JPEG and TIFF in about 1/20th, time to spend it as a Windows Flash program to accomplish its task.

  I also learned that seamer works better on text files and not so much on image files.  Indeed, a compressed jpeg file is about the same size as the original file.  A compressed tiff file password 137 mb 125 MB so some, but not much.  Why it takes so darn long comes mainly from transfer images JPEG in a different folder Windows is beyond me.  I assume that 7-Zip goes account that it does nothing more than to transfer them on and done it gets about as fast I could rename the original folder.

  Minimally, TIFF, 7-Zip compresses and gets it done almost immediately.  Windows takes 30 minutes or more.

  Discussion was going and came on whether or not would help more RAM.  The consensus is that it is not useful.  What helped was to use 7 - Zip.

  I also tried to pass like a Flash on a different computer on W7, I (an older i5 which has a four true cores) and it was slower in the Windows program as this computer.  This computer has an i3-2100, but has hyperthreading.  Given that 7-Zip can use hyperthreading maybe thats why it is so much faster.  Who knows.

• X 220 CPU speed problems

  I saw my CPU it's maximum speed of 3.4 GHz the first time I had used to hit. After download and update all drivers Lenovo & Windows, etc., the speed seems to be stuck at 797,3 MHz, no matter what I do. I did adjust the settings via the power manager. BIOS is 1.21. Any help on this would be appreciated.

  Edit: This seems to happen only when I'm on a/c without battery and when it's on battery power only. It is fine when I am on a/c with a battery.

  You must run the laptop with the battery, if you want the full speed, you may need to upgrade to the 90 Watt adapter.

• W540 First Impressions, CPU speed question

  I received my W540 yesterday, and I am still migrating throughout my W520.

  First impressions:

  (1) keyboard - works fine, no light on the hats of the key is not a problem, caps lock appears on the screen

  (2) track Pad - works great after a few adjustments to my taste

  (3) display LCD - pending

  (4) LED function indication - I miss indicators for the HDD, WiFi & Bluetooth Radios

  (5) weight - My W520 weighs 6.2 lbs, W540 weighs 5.6 lb

  Question of the speed of the CPU:

  I ordered the CPU i7-4930MC, which is supposed to work at 3.9 GHz. After changing the settings of the Power System Manager for "TURBO MAXIMUM", the speed of the CPU is always only show 3.20 GHz on system Properies. How to 3.9 GHz?

  Yes, it will not work at 3.9 GHZ at idle - it goes "turbo boost" as high as 3.9 GHZ on a single-threaded workload that requires a lot more speed, but most of the time, it is going to be lower to save on battery power, cooling, etc.

• download PC speed limit

  I have a HP DV7 laptop.  I use Brighthouse internet service.  I have just upograded ti their 60 MB service.  My PC does not seem able to get the nore to 45 MB to download.  Which is the limit for this computer?  Brighthiouse sent a technician with a newer pc, and it had a speed of 65 MB.  BrightHouse will offer even higher speeds and I want to know if I can take advantage of them.

  Thank you... Wizzcom

  Thanks for the information.  I talked to a technician at HP and the result is that my system can download a maximum of 45 MB.  I just received notice that Brighthouse now offers 90 MB.  What a shame, I can't enjoy it.

• XPS 15 9550 CPU speed is as low as 0.75 ghz after manually installed windows 10 with all the drivers installed and BIOS updated

  I just bought this XPS 15 9550 in January, and I really appreciate it at first.

  However, one day, as pushed microsoft update to 10586 version of windows 10 and the machine will always fail to install the update, so I decided to download the image file and install it myself.

  The installation went smooth, but after a few days use, I found the computer is very slow during playback of videos and games and I came to find the speed of the CPU shows the label of performance in the Task Manager always will be 0.75 ghz and 0.78 ghz. He cannot go above that. I also found that the use of the CPU cannot exceed 30%.

  I've already updated my BIOS to 1.1.19, reinstall the system, a few times, choose the battery mode high performance, etc and this does not help.

  I also downloaded the power of intel and found gadget for my processor power consumers are still weak and the speed of the CPU is always not 0.80 ghz.

  In addition, I encountered the problem that after plugin the AC power, the speed of the CPU will fall to 0.39 ghz...

  Someone at - it an idea of what is happening here and how can I solve the problem? I'll really appreciate it. Thank you.

  I had my problem is solved. Follow these steps:

  1. download gadget power intel, you can search online for it.

  2. check the power of your CPU (package pw...) rate and open the videos and applications that will constantly consume the CPU power. See if the power is still weak.

  3. If the power is still weak, try to update your BIOS (download dell drivers and the new version should currently be 1.1.20) and see if things are getting better.

  4. If the power is still low, you must contact dell technical service to replace your hardware (my computer has replaced the northbridge, southbridge, I forgot, but after replacing, the CPU works fine)

  Note: If you run games using your discreet graphics card, such as starcraft II and you found that it's extremely slow, it is possible that your cpu is capped.
