Endpoint Protection

Our health system has been using dell machines for years, and i would estimate we've had sep in place for at least 1-1.5 years. recently we have had an issue with dell optiplex 755's and performance. on 3 different machines in the last week, each machine (w/ 1gb ram and xp sp2) experienced slowness that made it feel like it only had a single 128 stick of ram. everything we tried to do was dreadfully slow. i cleaned up any unnecessary items from the startup menu, upgraded to sp3, and ran multiple system scans (chkdsk, sfc /scannow, spyware scans, etc) THESE MACHINES WERE CLEAN!! i ended up uninstalling SEP and immediately the problem was fixed. we still have SAV on some machines, so as a bandaid we installed it for the time.

finally i searched these forums and it was suggested i had bad optical drives. removing the cables on 1 machine w/ SEP still installed did not fix the slowness, but changing the bios setting from AHCI to Legacy DID resolve the issue.

i am now finding our Dell Latitude d820 and d810 laptops w/ 1gb of ram are noticeably slower. SEP is the problem, no doubt about it, but this was something that just began happening in the last 2-3 weeks. was there an update from windows and/or Symantec that caused this? does anyone else notice Dell machines are awful when Symantec products are installed? are there any temp files created by SEP that pile up and cause this?

any help is welcome

thanks

Have a look in below doc any suggestion in this can help you?
 Symantec Endpoint Protection Client configuration changes for performance optimization

We have seen issues of DELL optiplex  having BSOD or randomly shutting down after installing SEP. I have not seen specfic performance issue on DELL.

Follow the article suggested above and see if that helps

SEP does not create any temp files that may cause issues.

Also what is the version of SEP that is installed?

My company runs on Dell. Have seen some issues on all makes (240s, 260s, 280s, 620s, 745s, and 755s) dealing with slowness, in some cases we traced it back to SEP but they were usually on an older version and the upgrade fixed it. Other times, it was somthing unrelated. We had one location that was on version 11.0.4 and was being decimated by the 100% CPU usage when idle, uprading to 11.0.5 fixed the issue. If you're not on 11.0.5 I would suggest upgrading first.

What SEP version are you running on your clients and server? How was it deployed? Do you perform version upgrades by group via the console?

We have seen an occasional issue where clients which were originally installed with SAV by GPO, then upgraded by GPO to SEP MR2 MP1 had poor performance. Upgrade to MR3 and subsequently MR4 etc improved performance except for a very small number of users who continued to complain. Manual uninstall of MR4 MP2 and reinstall gave a dramatic performance boost. We are a mostly Dell house but it did not appear to be specifically a Dell issue. And it was a performance issue there from day one, not something which came in after a period of acceptable performance.

we are on 11.0.5 currently

so, the culprit here was a massive load of temp files of some kind. our sep admin wrote a script to go through and clear out temp files from sep for all users. on most/all it finds nothing, but on the 755's, the folder was LOADED w/ these, and it was an immediate difference.
