Slow performance after installed ZENworks 11

Hi,

Does anyone here facing overall slow performance on booting up (every time), Slow Login after enter the Login password, Slow in opening an application and etc?

Is there any tweak available for me to make the performance burst up ?
I have uninstall by uncheck ZESM and Image MGM, and disable Remote MGM, but my user still keep complaining the overall performance is unexpected.

SPEC:
C2D, 4GB RAM, Windows XP.


thank you.

Re: Slow performance after installed ZENworks 11

Hello,

- Unchecking ZESM in ZCC only disables it showing on the client, its still installed and active, its used for the Location Awareness engine.
- What policies and how are they built up on the workstation, especially DLU's with file permissions and standalone FileRights policies. (Setting DLU's with filerights is BAD for performance)
- How many computers are being slow, you only say that ONE user is having the issue... Is the specific user connected via LAN or WLAN? Is the specific user connecting via WAN ? How is your serversetup, how many primaries, satellites, backend DB if any, etc.

What overall "kind" of performance? Is it only .Net applications? Do you have a content proxy for HTTP(S)?

Re: Slow performance after installed ZENworks 11

We are facing the same issue on all our workstations using ZCM 11. We have only 1 primary server at this time, but so far only 30 machines using it. Each computer used so far ranges from a P4 2.4Ghz to Core2 Duo all with 1.25GB Ram. All have 100MB connections back to the same switch the ZCM 11 server is on. The only policys we are running is a simple DLU, ZEN Explorer, and Windows Group Policy (but that was added after the slowness).

Re: Slow performance after installed ZENworks 11

What kind of specs are there for the primary server? What kind of database backend? Does the clients have internet access?

In our case the backend server is a VMWare hosted server with 4GB of RAM, 1GB network, Intel Xeon 2.83Ghz Processor, using the Sybase database installed with ZCM on SLES 11

Re: Slow performance after installed ZENworks 11

Ok, that might be an issue, depending on what you think is slow. In my LAB's I never go with Sybase internal or external, personal preference due to its so slow. Using a VM with Oracle or MSSQL is a great deal faster than Sybase.

What is slow at the moment if I may ask that, be detailed 😉

Mostly user complain about slow once ZAA has installed. Users are using LAN
1 Primary
1 Satellite both server in the same site, users in the same site as well.

Windows Boot slower, Application launch slower, Login from Welcome screen slower and etc.
and Yes, We are using Proxy server to connect to outside world. However, some application do not require to connect outside world such as Microsoft Word.

Another Example, A user using C2D, 4GB RAM could open 12 Excel in the same time. But once installed ZAA, There is some delay when launching 12 Excel.

Re: Slow performance after installed ZENworks 11

If you disable ZESM, you will also disable the location awareness engine.
Imaging service could be disabled via ZCC instead, if you dont intend to use imaging bundles that are transferred via PXE to workstations rather than HTTP when the user is logged onto the OS.

No DLU? Precreated users in Windows then? Or is it AD?

The reason I ask if you use a proxy, is because there is authenticode signed code in .Net, which is one of the buildingblocks in ZAA. It tries to verify the certificate the code is signed with to external servers, like VeriSign. If you have a proxy that needs to be manually configured like proxy:8080(ie, not transparent), it may cause issues(in my office, it does). How does the user launch Excel, through the normal .lnk or through NAL shortcuts?

Re: Slow performance after installed ZENworks 11

Open an SR with Novell if you want to remove ZESM from clients (and loose Location Awareness Engine), I have not had any good results doing it on my own.

Normal LNK should not be affected when ZAA is installed, could you measure the differnence? Or even better, do a trace with ProcMon and see what it does differently between plain PC and ZAA on PC?

Re: Slow performance after installed ZENworks 11

I've been running procmon for several bootups now, and I've found that
colw32.exe has A LOT of file activity when the machine starts up. We do NOT
have inventory configured to run during the day, and we do NOT have it set
to run if it was missed. Yet, it seems that on each boot, colw32.exe is
grinding away looking for things on the hard drive. We've added many, MANY
exclusions to our AV software (the ones recommended by Novell + more), and
we've pretty much ruled out AV causing the slowness. Our ZCM 10.3.1 agents
don't have these long logins, but our ZCM 11 agents do.

Can anyone else confirm or deny that colw32.exe is doing a lot of work on
bootup?

Re: Slow performance after installed ZENworks 11

Oh, and I will say that this client was NOT updated. The ZCM 11 Agent was
freshly installed with the Cumulative Agent 1.

I don't see colw32.exe kicking off for me, though I have no doubt you
are seeing it.
