Kerio Connect 9.0.3 decided to re-index the full-text search however it is taking an extremely long time. It only seems to be processing around 3 users per hour. On a system with 250+ users you can imagine it's taking a while.

CPU/RAM/Disc utilisation don't seem excessive and Kerio Connect Client itself seems to be behaving fine.

Any ideas?

Cheers Smile

There are some options in the mailserver.cfg you could try. But do a backup or snapshot first. And don't forget to restart the services.

<table name="FullTextSearch">
<variable name="Enabled">1</variable>
<variable name="StartTimeout">20</variable>
<variable name="Path">E:\Kerio Connect\MailServer\store\fulltext</variable>
<variable name="IndexArchiveFolders">0</variable>
<variable name="IndexerCacheSize">3</variable>
<variable name="SearcherCacheSize">5</variable>
<variable name="IndexMergeFactor">10</variable>
<variable name="DebugLogLevel">0</variable>

But honestly - it can take some time. Kerio saves all mails as single file, so the fulltext has to open the folder, scan it, scan the files etc. - and if the scan is not multicored, it just needs its time. With 250 users on the system, there should be quite the i/o and reading the files for the index needs even more time (random access won't really let you hit a 100% activity rate, because of the search etc.).

Also if the users are like ours and have like 50k mails per folder ... well... Very Happy
