Zimbra Web Client slow...

[Enake]

Hello everybody ...

From the web client users complain of slowness to:

- Open messages.
- Send messages.
- Save appointments in the calendar.
- Delete messages.
- Move messages between folders.
- Empty Trash folder / Spam folder.
- Add attatchments.

Navigation is normal, change between folders or between Calendar/Contacts/Tasks... is very fast.

The only way I have to fix it by restarting the server. Once rebooted go fast, but after a few days slow reappears.

I recently added two more gigabytes of RAM, total of RAM now: 3 GB.

Only 1 processor with HT enabled in BIOS and in the Kernel.

What is the output from

zmlocalconfig | grep mailboxd_java_heap_memory_percent

[Enake]

Hi uxbod.

mailboxd_java_heap_memory_percent = 40

Here is the output.

Regards.

[uxbod]

You could try tuning back the amount of memory java takes using

su - zimbra
zmlocalconfig -e mailboxd_java_heap_memory_percent=30

and then restarting ZCS.

[Enake]

Hi...

I restart the ZCS with zmcontrol stop and zmcontrol start and the problem persist.

If you want uxbod, I can realize a video with Wink before and after the server reboots...

Regards.

[uxbod]

Are you using the Ajax or standard HTML client ? If you use the HTML one does the issue persist ?

[Enake]

I am using the Ajax version.

In the HTML version, the issue persist.

Regards.

Is your ZCS server on the same LAN as the clients ? Do they go through a proxy at all ?

[Enake]

OK, I have the videos...

Perhaps you can identify the problem better.

In the first video the mailboxd_java_heap_memory_percent is set to 30 and the server was up for 6 days:

In the second video, the mailboxd_java_heap_memory_percent is set to 40 (default value) and the server is up for 15 mins:

http://www.enake.net/zimbra/after_re...ter_Reboot.htm

You can see the huge diference... I don't know what thing is causing this problem...

Regards.
