New Scalix 11.2. release

[treedstang]

Do any know if the latest Scalix 11.2 release offer any huge performance improvements over the older version of the 11.0 series.

I have 18 users on a 11.0.4 release and I have been battling performance issues with SWA since the beginning

SWA is almost unusable especially on larger mailboxes I'm using the the community release.

I've done all the tweaks I could find here in the forums.

Any insite would be helpful

No the performance is the same. I don't think this will change untill the server starts cataloging the mailboxes in "real-time" at the messages are delivered or moved.

[treedstang]

Could you please share some in site on the cataloging process . .. Maybe I can try that


Thanks

[pharoh]

no I am sorry I meant "if" the server had this feature.

pharoh, out of curiousity how is your SWA performance ?? and what are you doing for performance tweaks?

[pharoh]

We do a few things:

we give as much memory as we can to java (usually 512-768)
we allow multiple imap connections
we run a cron job that omtidyallu -M every day to lessen the first login of the day time.
we also run in a MINIMUM of a raid 10.

off the top of my head that is all I can think of.

but SWA is still unusably slow when you have over 4000 messages in a single inbox and or sent items. (we have begun to get users to place messages in subfolders by year which helps alot)

what kind of disks are you running. We found scalix to be very diskbound, firstly we moved the temp folder to a separate volume (which helped a bit) and now finally we've moved to an external storage array which seems to be noticeably quicker opening mail.

also make sure that omscan is not running during the day.

the biggest thing we found to improve performance was reducing the number of items in the inbox. putting things in subfolders really seems to help. we had a couple of users with 12000 mesage items in their inbox which took forever to load.

we are currently using sata II local storage but have used SCSI ultra320's as well. We toyed with moving the temp volume but the single biggest increase in noticeable performace to the end user was moving to sub folders and keeping the folders as close to ~2000 messages or less. deleteing the smart cache and re-creating on 11.2 seemed to increase as well but I have no benchmarks so it may just be perceived.

How does one delete smartcache and re-create? Just delete the mail profile (in Windows) and use the "Prepare SmartCache"-button in SAC or?

Thanks,
Kimmo

[pharoh]

we did both recreate sis index and smartcache buttons in sac.

Hi Kimmo,

Yes, you need to delete your old Outlook SmartCache profile and create a new one. If you 'Prepare SmartCache' from SAC before you create the new profile then the Cache-Init phase will run more quickly (but you don't have to do the 'Prepare Smartcache').

An alternative to clicking the 'Prepare SmartCache' button in SAC is to use the command line:
sxmbcprep -u <user>
before the creation of the new profile (although as aI said before this only speeds up the Cache-Init, and isn't essential).

Cheers - Richard

Can you log into the mobile client?

Slow SWA is almost always a problem with the PostgreSQL configuration, and the easiest way to see that is to check if you can sign into the mobile client.
