LSI SAS 9211-8i performance problem. (2 MB/s)
Hello
I got the LSI SAS 9211-8i adapter to implement an ESXi 4.1 server to host a set of virtual machines.
I attached 8 6 GB/s Western Digital HDDs to the adapter and put into RAID 10.
Everything was OK during the installation and initial configuration, but when it came time to transfer all the virtual machines in this
individual ESX server, the best data transfer rate was somewhere between 2-3 MB/s.
I've already updated the BIOS and the firmware in the adapter, but still no luck getting it to transfer more quickly.
Only time wherever I was able to get improved data transfer speeds was when I removed the RAID and had all 8 disks individually,
But even in this case, the performance was so-so. (4-5 MB/s).
NOTE: If I connect a hard drive to the motherboard and install ESXi 4.1 on the disc, the speed of data transfer are very good.
Data sheet:
---------------------------------------------------------------------------
Motherboard: ASUS P6X58D-E
Processor: Core i7 950
RAM: 24 GB DDR3
hard drive: Western Digital WD5002AALX
NIC: Intel PRO/1000MT
---------------------------------------------------------------------------
I would really appreciate if anyone has ideas or suggestions.
Kind regards
Mikey
Yes, it is built to a price. There is nothing wrong with it. LSI has just removed features (cache and the option to add it) to make it to sell for a price conscious buyer.

I changed my scsi lsi sas to pvscsi adapter, but then the 2012 server will not start. What is the process to change the adapter? Is there a great performance benefit to LSI sas to pvscsi?
Thank you
RDM will be still less resources than VMDK. This may not always translate into better performance. In this case, you really have to do a few tests to decide what will be the ideal combination for your specific virtual machines. But, Yes, MDM with pvscsi must have the best performance of all the scenarios.

Hello
MY Z820 workstation is equipped with an Intel 520 240 GB SSD as boot drive, on the integrated LSI SAS 2308 controller. It is a GPT disk.
I just tried to update my BIOS Rev 02.08 Z820. at 02.55 a. rev.
The update succeeded, and in the BIOS, I check that all the settings are the same as before the update. On the boot, however, I get an error saying "Non system disk or disk error."
Mass strorage option ROM is set to EFI mode.
No matter what the settings, it does not start in Windows.
I started 02.08 BIOS Rev A and now all is well again.
Is there a compatibility issue with the BIOS 02.55 Rev A combo, Intel SSD 520 and LSI SAS 2308?
Kind regards

LAST UPDATED:
The Z820 motherboard was faulty. A HP technician swapped the moherboard with a new one and now all is well again!
The storage controller was indeed defective.

WRT54GS - wireless performance problem
Dear someone
I am currently having performance problems with my WRT54GSv1.1
Just received my new internet connection to 30Mbit. Unfortunately, I am not able to download at that speed. If I connect via one of the linksys router's ethernet ports, I'm a happy person, but using the wireless makes me a little less happy.
Wireless: 15Mbit/s
Through the cable: 27Mbit/s
Network information:
The distance between the router and the computer laptop 3-4 meters
Linksys WRT54GSv1.1 - Firmware Version: v4.71.4
Network wireless - g only mode
TV - 6 (because all the surrounding neighbor use 10-11, I noticed using Cain Abel & wireless discovered 4.9.29)
Security: WPA2-Personal (TKIP + AES)
All other settings are default (just reset to the factory settings).
Laptop:
Windows Vista Business SP1 32-bit
Intel PRO/Wireless 3945ABG (installed the latest drivers from the website of intel, default settings)
When you check the diagnostic of Intel tools, it tells me the link is 54 megabits and pushes meter packages of 54 megabits, while all lower speeds remain the same.
More diagnostic information:
Percent missed beacons: 0
Percent transmit errors: 18
Current Tx power: ~ 32 mW (100%)
Supported power levels: 1.0 mW - 32.0 mW.
Hope someone can help me here.
Thanks in advance!
Kind regards

Although wireless g "connects" to 54 Mbit/s, the maximum possible wireless "data rate" (in ideal laboratory conditions) is only about 20 to 25 Mbit/s. Unfortunately, the phrase "in ideal laboratory conditions" generally excludes home intrusion!
The aerial transmission for wireless connections is higher than for wired connections. Thus, most individuals find that their Wi - Fi connection works at 50% to 70% of their speed of wired (LAN). Your wired LAN being 27 Mbps connection speed, your 15 Mbps wireless speed is within normal limits.
You might be able to tweak a bit more speed from your wireless network by optimizing all your wireless settings. Here are a few suggestions:
I guess you want actually to WPA2 encryption. If so, set to AES only. When you set the router to TKIP and AES, you actually tell the router to accept a WPA or WPA2 connection.
Also, give your network a unique SSID. Do not use "linksys". If you use "linksys", you can try to connect the router to your neighbor. Also set 'SSID Broadcast' to 'active '. This will help your computer to find and lock on the signal from your router.
Bad wireless connections are often caused by interference from other 2.4 GHz devices. This includes cordless phones, baby monitor wireless, microwave ovens, wireless mice and keyboards, wireless speakers and wireless network from your neighbor. In rare cases, Bluetooth devices can interfere. Even some 5 + GHz phones also use the 2.4 Ghz band. disconnect these devices and see if that solves your problem.
In your router, try another channel. There are 11 channels in the band of 2.4 GHz channel 1, 6 or 11 generally works better. Discover your neighbors and see what channel they use. Because the channels overlap, try to stay at least + 5 or - 5 channels of your more powerful neighbors. For example, if you have a powerful neighbour on channel 9, try any channel 1 to 4.
Also, try putting the router about 4 to 6 feet above the ground in an open area. Do not place behind your screen or other computer equipment or speakers. The antenna must be vertical.
In addition, in the computer, go to your wireless software and go to 'Favorite networks' (sometimes called 'Profiles'). There are probably a few listed networks. Remove any network called "linksys". Also remove any network that you don't recognize or that you no longer use. If your current network is not listed, enter its information (SSID, encryption (if any) and key (if any)). Select your current network and make your network by default, then set it to auto login. You may need to go to 'settings' to do this, or you may need to right click on your network and select 'Properties' or 'settings '.
If you continue to have problems, try the following:
For wireless g routers, try setting the "baud rate" at 54 Mbps.
If you still have problems, download and install the latest firmware for your router. After an update of the firmware, you must reset the default router, and then configure the router again from scratch. If you have saved a router configuration file, DO NOT use it.
I hope this helps.

Oracle 9i Java component performance problems
Hello
I am reorganizing a java component inherited because of performance problems.
A java stored procedure is used to trigger a shell script that runs a java component. The component connects to a series of remote directories via ftp, gets the files and load them using slq * charger.Is there a better way to do this? I saw a few articles talking using a FTP interface directly from PL - SQL jump the java component entirely. It would be preferable to the current solution its?

ViewObject range Paging performance problem
Hi all
I am facing a performance problem with the implementation of an obligation to programmatically add a number of extra where the parameters of the clause (using bind) variable in combination with range paging.
My code looks like this
... ApplicationModule am = Configuration.createRootApplicationModule("services.DossierAM", "DossierAMLocal"); ViewObject vo = am.findViewObject("DossierListView"); // apply programmatic view criteria ViewCriteria vc = vo.createViewCriteria(); ViewCriteriaRow vcr = vc.createViewCriteriaRow(); vcr.setAttribute("Reference", "15/%"); vc.addElement(vcr); vo.applyViewCriteria(vc, true); // enable range paging vo.setAccessMode(RowSet.RANGE_PAGING); vo.setIterMode(RowIterator.ITER_MODE_LAST_PAGE_PARTIAL); vo.setRangeSize(50); vo.scrollToRangePage(5); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled // vo.scrollToRange(250); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled ... ...
I found 2 solutions, but they both require an application of additional database that is, performance wise, is not acceptable.
The first solution is to slip into an additional call to exectueQuery() before the call to function scrollToRangePage (int) or scrollToRange (int).
The second solution is to use the method (int) setRangeStart instead of variants scrollToRange (Page). This method performs also 2 database calls.
My question to you:
Is there another way to satisfy the requirement of programming add a certain number of parameters of the additional where clause (using the variable binding) in combination with the pagination of the range without the need to perform queries of database 2?
The code is tested with JDeveloper, 11.1.2.4.0, and 12.1.3.0.0 and behaves the same on both versions.
Kind regards
Steven.
Have you tried to create truly VC with bind variable (rather than use binding implied var created by frame)?
Something like: http://www.jobinesh.com/2010/10/creating-view-criteria-having-bind.html

Performance problems since the update of 2015.6
Hello together,
Since I updated lightroom yesterday to version 2015.6 the performance on my machine is incredible bad.
My system:
-MacBook Pro (retina, mid-2012)
-2.3 GHz Intel Core i7
-16 GB 1600 MHz DDR3
-NVIDIA GeForce GT 650M 1024Mo
-OS X El Capitan (10.11.5)
Lightroom synchronizes actually 1400 photos, but even if I stop this process, LR uses CPU so I can't work in other programs like Photoshop (updated yesterday, too). I detected this performance problem as PS freezes when I used the Healing Brush tool.
I don't know what's happening LR, but is not ideal for my workflow.
Does anyone have an idea?
If I close LR I can work in PS, even though the Healing Brush tool is slower than in the version before. But I can't always close and open LR.
Thank you
regards Denis
There are already dozens of threads discussing the same question in this forum as well as in the official comments forum here: https://feedback.photoshop.com/photoshop_family/categories/photoshop_family_photoshop_ligh troom
You can restore 6.5.1 if you wish. Here's how: How do I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1? Lightroom Queen
Just replace 6.1.1 with 6.5.1

HP Pavilion 15-n005sg: performance problems and worsens
Hello
I bought this PC here is a year, has been a very good PC with good performance, but has been doing more and more slow to the month, for example, I used to run Diablo 3 on average - high specification with 60 fps constant with no performance problems, but that in the end, I can't still running at ultra low care without screen freezes and fps drops to 1-2 as well as the League of legends and other games.
It takes more and more time for my pc to turn on, which was like 30 ~ 40 seconds not takes like 3 minutes.
the performance gets really bad and should not happen on a pc of 1 year.
What can I do?
An update of the system may be your best course of action.
Your data, files, etc. will be retained. Any Windows apps store is kept.
Any program that came pre-installed is preserved.
BUT all programs which are not in the above categories will have to be resettled; your games, printer, etc.

Performance problem - oracle 10.2.0.4

Hello
I have a performance problem involving high line response to locking conflicts that I can't wait.
The application updates the specific table about 1200 times for my AWR report representing 2 hours.
This update represents 98% of the db_time and wait to enq: TX - line lock conflict is:
-83 796 waiting
-245 441 seconds
The application updates a row both an unprecedented SELECT UPDATES. This is the query:
Update my_table set creationtime =: 1, modificationdate =: version 2, =: creationuserid 3, =: fortesting 4, =: 5, modificationuserid =: participation_uuid 6, =: actimenucontact 7, =: allegroid 8, =: campaign_uuid 9, =: desjardinsemployeetype 10, =: effectiveparticipationtype 11, =: family_uuid 12, =: fetchpasseport 13, =: 14, healthratingfilldate =: hoursofsleeptimecommitment 15, =: igaid 16, =: initialsubscriptiontype 17, =: minutesofsleeptimecommitment 18, =: goal 19, =: partner_uuid 20, =: 21, promotionalemails =: 22, readrules =: sccsubscriptionprovenance 23, =: = subscriptionprovenance 24,: 25, supportemails =: where the 26 uuid = : 27 and = version: 28
Clause where is filtering on uuid which is the primary key of my_table.
The uuid is a specific user and two users would not update the same row, what could be the reason for this wait event?

Why guess when you know.
Watch ASH data for these events to the queue.

took vcap5-dca exam today and had laboratory performance problems
Most of the time, the review ran ok. I was very impressed by the performance of the lab environment. I can say that I had to skip two questions I knew because the keyboard and mouse of entry would not work. After spending 5 minutes trying to get my keyboard and mouse works on one of the questions, I had to jump even if I knew the answer. It is unfortunate that, for a review of 400 dollar, you have performance problems that limit your ability to perform the review. Overall, I think I did pretty well. I was able to get about 19 questions answered to jump through the other 7 due to the performance and time. I acknowledge that the pace I started to was a bit slow, but laboratory performance degrade my ability to perform my best on this review. I would recommend to anyone who takes this review to make sure that you use a good test center. I drove 60 miles to my test center to make sure that I went to a good and always fell on issues. I could only imagine what it would have been like if I went to one of these centers of samples of groceries with a metropolitan WAN connection for internet :-) Now wait to see if I've spent 15 days.
Has anyone else had this kind of questions? If so, where did you register a complaint?
Hello
The delay is a common thing for everyone outside the USA. She varies the amount of delay but it has been around since the VCAP-DCA 4. In regard to complaints they should normally be done the day of the test to the exam administrator otherwise pearson cannot do much.
Good luck for the result!
