• impact on the performance of the vmware tools

  We had discussions about the performance impact of the installation on a virtual machine vmware tools.

  Are their any comparison between a system running vanilla versus a running vmware tools installed?

  Obviously, I think that the system will go faster with vmware drivers installed.

  Tools will only help IO performance (not counting usually do things like graphics and synchronization times work better).  If your virtual machine has no important networking or storage needs, then you probably don't need the tools.  I'm usually not worth.

  If you want very good performance network without tools, make sure you use a device virtual e1000.  You can define ethernet0.virtualDev = "e1000".  This is not quite as good as real vmxnet (or new vmxnet3) but is much better than the default vlance. If you regularly push 1Gbit or more real traffic to your virtual machines, I would consider it.

  Paravirtualized SCSI is fairly new, but since I have seen that there is a performance gain enough points of reference.  But even once, most likely you need not, unless you use a disc very heavy VM I/O, such as an Oracle database server.

  If you consolidate underutilized physical machines who never use 100% CPU/network/disk, then Tools are probably a waste of time.  But if you want as close as possible to performance native and CPU utilization during intensive i/o, then Tools are worth.

  As for Redhat don't support our drivers for VMware tools, I don't see why this would practically be a problem-if you have any question/crash that you think may be related to our tools, you can always uninstall and go back to where you were before.  If you have an unrelated question, and you are worried Redhat refused to help with tools, you can do the same thing.  So what's the harm in trying them?

• Impacts on the performance of the attributes from the features of data model design

  I'm trying to understand the implications of the performance of two possible data model design.
  
  Here is my structure of the entity:
  
  Global > person > account > option
  
  Generally, when running, I instantiated a person, a single accountand five option's .
  
  There are various amounts determined according to the age of the person who should be assigned to the correct option.
  
  Here are my two designs:
  
  Design a
  
  attributes on the entity of the person :
  age of the person
  its option 1 amount
  its option 2 amount
  its option 3 amount
  its option quantity 4
  its option 5 amount
  
  attributes on the option endity:
  amount of the option
  
  support table rules:
  option = amount
  its option 1 amount if the option is number 1
  its option 2 amount if the option number 2
  its option 3 amount if the option number 3
  its 4 option amount if the option is number 4
  its option 5 amount if the option is number 5
  
  Two design
  
  attributes on the entity of the person :
  age of the person
  
  attributes on the entity of the option :
  amount of the option
  of the option option 1 amount
  of the option option 2 amount
  of the option option 3 amount
  of the option quantity 4
  of the option option 5 amount
  
  support table rules:
  option = amount
  of the option option 1 amount if the option is number 1
  option 2 amount option if the option number 2
  of the option option 3 amount if the option number 3
  the option amount 4 If the option is number 4
  option 5 option amount if the option is number 5
  
  Given two models, I can see what looks like an advantage for a design that, when running, you have less attributes (6 on retirement member + 1 on each of the 5 options = 11) as two Design (1 on retirement members + 6 on each of the 5 options = 31), but I'm not sure. An advantage to design two might be that the algorithm must do less through the structure of the entity: the table of rules support everything for the amount of the option option.
  
  Anyway there is a table of rules to determine the amounts:
  
  Design a
  its option 1 amount =
  2 if age = 10
  5 if age = 11
  7 if age = 12, etc..
  
  Design two
  of the option option 1 amount =
  2 if age = 10
  5 if age = 11
  7 if age = 12, etc..
  
  Here, it seems that the one would have to cross over the structure of the entity for the design of two.
  
  The design will have a better performance with a large amount of rules, or it would make a difference at all?

  Hello!

  In our experience, just think about this kind of stuff if you were dealing with 100's or 1000 instances (usually through ODS). You have a very low number, the differences will be negligible, as you should (in general) go with the solution that is most similar to the material of origin or the understanding of the business user. Also, I guess that's an OWD project? Which may be even better, the inference is performed gradually when new data are added to the modules, rather than in a 'big bang' as ODS.

  It seems that the model 1 is the easiest to understand and explain. I wonder why you have the option at all entity, because it seems to be a relationship to one? If the person cannot have only a single amount of option 1, option 2 amount etc, and there's only ever going to be (up to) 5 options... is this assumption correct? If so, you can keep just like the attributes at the level of the person without the need for bodies. If there are other requirements of an instance of the option then, of course, use them, but given the information here, the option feature doesn't seem to be necessary. It would be the fastest of all :-)

  Whatever it is, that the number of instances is so low, you should have nothing to fear in terms of performance.

  I hope this helps! Write back if you have more info / questions.
  See you soon,.

• Problem with an "unknown device" having an impact on the performance of the pc

  Hello world! My name is Lorenzo, and I am currently having problems with my laptop, a HP Pavilion dv6, 64-bit laptop running Windows 7 that runs more slowly.
  At first, I thought that the problem was a malware, so I decided to follow this procedure: http://www.techsupportalert.com/content/how-know-if-your-computer-infected.htm.
  I tried TDSSKiller, Comodo cleaning Essentials, Killswitch, Malwarebytes, Hitman, Combofix then I installed Driver easy to update the drivers but it doesn't change anything.
  Even repairs Windows or Windows Fix it does not solve the problem.
  This is the message I get from Tune Up Utilities: Windows reports the "A2 Direct Access Driver Support disk" device does not work correctly.
  When I open the Device Manager and try to manually update the device it doesn't seem to work; the same thing happens if I disable it or uninstall it and restart.

  Well first, uninstall the update of the pilot program, using such will only cause problems. Drivers for your laptop are available free of charge at HP, nore if you use windows update for drivers.

  And then uninstall Tune UP utilities because it is only likely to cause other problems. Win7 contains all of the built-in tools in order to maintain the system.

  The "A2 Direct Access Support disk driver" part of Emisoft Anti-malware, you have this program installed?

  And in the future do not try to update something on that you don't know anything

• Measure the performance impact of a PowerCLI report on vCenter

• East-audio/video or advertising photos in the tab 'not open' affect the performance of Firefox?

  From what I understand the audio Forum leaking by a tab can be cut. This means that the most important activity such as periodic updates on a page to download advertisements could also affect Firefox performance even if the tab has not been clicked. Is this true?

  Once the tab has been loaded, any video or audio active in this tab will have a negative impact on the performance of Firefox.

  In the options, you can tell Firefox to not load the tab until it is selected, but once you select the tab for the first time, the site will remain responsible.

• Impact on the Thread.sleep processor

  Hi all

  Someone knows what this impact of the Thread.sleep on cpu perfemance BB?

  Thank you

  UDI

  Thread.Sleep simply takes the current thread on the Scheduler to send for a certain period of time.

  I guess my best answer is that there no direct impact on the performance CPU - CPU runs all the time, at the same speed than it was before.

  Hi Kiki,

  These kernel parameters affect the performance. They will simply affect how much shared memory, messages and semaphores are configured in the kernel. This could affect whether a particular TimesTen data store can be loaded into memory or not, but if it charges so that they have no real effect on the performance.

  The difference in performance is due to this:

  model name: Intel(r) Xeon E7540 CPU @ * 2.00GHz*
  step by step: 6
  CPU MHz: * 1064.000*
  cache size: 18432 KB
  CPU cores: 6

  in relation to this:

  model name: Intel(r) Xeon E5620 of CPU @ * 2.40GHz*
  walk: 2
  CPU MHz: * 2400.000*
  cache size: 12288 KB
  CPU cores: 4

  The second machine has a significantly faster processor...

  I check I can pass a Variant to a Subvi with a copy, but it is still impossible to do something (scaling limit controls etc.) with a Variant without first copying it in a new buffer the conversion 'of the Variant.

  Thus,.

  For large sets of data, the variants are a bad idea.

• KB973687 - msxml3.dll msxml6.dll - services.exe uses excessive virtual memory, the performance impact on the first logon after restart

  Since the installation of fix KB973687, I had several SP2 and SP3 systems exhibit behavior that makes them unusable until after the first logon is completed, which can take up to 20 minutes.   I've identified the patch (KB973687) and DLLs, that it will update the origin of the problem, but uninstalling the patch does NOT return to normal operation.

  I need to understand how to upgrade these systems WindowsXP SP2 and SP3 to restore normal operation, reinstalling Windows, programs, and settings is an expensive solution.

  The performance problem is caused by services.exe slowly consumes about 1.5 GB of virtual memory, and then slowly releasing.  This seems to be triggered by the first logon after restart, this connection is very slow, the screen is blank for most of it, there might be failures of allocation memory during logon.  Once complete this opening of session and memory usage returns to normal levels, recording and return to work normally as do other operations until the system is restarted.

  Spent a lot of time working with SysInternals Process Explorer, trying to find what specific service might be involved, lightweight system for bare essential services with no luck.

  KB973687 seems to offer only two files msxml3.dll and msxml6.dll.  Uninstalling this patch, resettlement V3 and V6 of the XML parser fail to restore normal operation.

  Not all systems seem to have place still restrict the differences.  Systems that are appear to be the oldest, with Windows XP has been installed for at least a year, installed Microsoft Office and Adobe Acrobat.

  Looking for these forums and the Internet, I believe that many have encountered this problem, but have not is it this level of analysis, seem most attribute it to a virus, I see several start explorer.exe manually, I didn't know all the alternatives before reinstalling Windows.

  Found the solution, the following has been fixed in System Cleaner of Comodo 2.2.129172.4:

  "For some strange reason, after changing some settings of the system with the CSC LastGood.tmp Directoy began to constantly be read from my hard drive. This would occur up to about 90 to 99% of my memory was used and then stopped, begin to free the memory, and the system began to slowly to function normally.
  I used the process explore from sysinternals to help diagnose the problem with any process other than services.exe using memory.

  I used sysinterals filemonitor to see LastGood.tmp directory has been read repeatedly.
  After you have uninstalled CSC the problem has been resolved. »

  Even with the effort to find the solution, it was better to reinstall.  Hope this solution helps others.

• power button will affect the performance of the system

  Mr President.

  I was forced to use the power button to turn off my laptop HP 2231tx G6 in certain circumstances. I would like to know if this will affect all my gear system & impact on its performance. Because mine is only a new system.

  Using the power button to turn off the computer will not affect the system hardware or your computer's performance. It can, however, lead to the system indicates that it "didn't stop in properly" and may require the system to the performance of a hard disk check before starting entirely. In addition, you can lose data by turning off the computer by this means.

  If you have any other questions, feel free to ask.

• Performance indicators? How to confirm the performance?

  I'm getting very concerned by the speed of copy/transfer files to and from the Media Hub.  I bought it mainly as a NAS, but maybe it was my mistake, I thought not performance would be as slow as it sounds.   I've seen the other comments on the performance, some answers have been pointing users to check their networks.  I would like to know if there are some points of reference which can be published so that we can compare against them.  Publish the test script and the results, then we can run the same tests and compare the results.  I can withdraw from my network and connect directly to a switch isolated for testing if necessary, but I'd rather not have to disconnect things and go through that effort if I can test everything first and see how far off I am standard expectation.

  If I can at least know what the performance of the target for this type of operation, it would help me to decide if I should invest several times in this or switch to a dedicated NAS.

  In addition, one of the things that I suspect a little is the Twonky Media scanning server.  I have it turned off, but have not yet restarted to confirm that I am in the middle of a great copy that looks like it's going to be two days.  Are there other parameters of Twonky can I disable in order to minimize its impact, or can I disable Twonky completely?

  Everyone knew the "performance impact' operation manager collects data from the virtual infrastructure?

  The collection runs only against vCenter and its PB or also against the hosts?

  Is vCops a potential performance problem?

  Eric-

  Agreed. We connect to 6 Server vCenter (related modes) in the world of our vCops US VAPP with no noticeable performance hit to the environment. As Chris pointed out analytics VM takes a big CPU reaches around 01:00 every day that she crunches numbers but to be provided.

• How to evaluate the impact of the removal of the CPU?

  One of my clients must remove three (of four) CPU in order to respect the license agreement with Oracle.
  
  To avoid problems and also for any problems remove the CPU can bring the list, I want to do a study on the possible impacts, especially in the performances, which can cause the removal.
  
  How can I get this information?

  >
  I really want to do all the tests and get concrete data on what is the real impact. The customer uses about 20% of his salary (cpu + cpu wait) but I know that this does not mean that it can simply cut their treatment at 25% safely.

  Yes, my client has a test environment, but does not have a database of the replay, so it is not possible to perform tests on the workload precisely.

  How can I test without this tool, or at least the collection of data that will give me more specific that CWA information? It should open a SR on MOS?
  >
  There is nothing to open an SR for.

  The type of system change, you're talking about can only be tested on a system that best matches the production system. It has too many interactions between the CPU, memory, cache and external (disk) storage systems to be able to use a system of unpaired test and extrapolate the results.

  You will have to do equivalent performance in order to obtain meaningful results, but these tests should be done on similar systems.

  If I were you I would start by contacting your Oracle support person and identify the actual costs to continue to use your system for 4-processor and costs associated with maybe a 2 - cpu system.

  Then I estimated costs of the work in question in any change of your test system to make it as nearly equivalent to the possible production system and add in the costs of running actually load tests and a fudge factor to take account possible downtime or a financial loss due to the degradation of the system if your estimates are erroneous.

  You find it's cheaper and less risky, to pony just upward at least a 2-processor license. Who would buy at least your client enough comfort and time to design a more reliable long term solution.
