Hello All,
I setup a Roundcube webmail, and it is working fine. Some part not but i can live with that. The problem is that my Server admin is complaining about mysql usage and threads that Roundcube make. I disabeled CACHE but that didnt help either:
/ enable caching of messages and mailbox data in the local database. // this is recommended if the IMAP server does not run on the same machine $rcmail_config['enable_caching'] = FALSE;
// lifetime of message cache // possible units: s, m, h, d, w $rcmail_config['message_cache_lifetime'] = '10d';
Readed that on forum: http://roundcubeforum.net/forum/index.php?topic=116.msg927#msg927
Here is list of thread that are on MySQL5

Actually, persistent connections could be the problem. PHP's implementation of mysql_pconnect isn't the greatest. That is why it was taken out of the mysqli connection.
According to the SHOW PROCESSLIST, it shows a lot of sleeping connections. MySQL's default timeout is 8 hours, so those could be there for quite some time.
I disabled persistent connections from the start and I have not had any problems. Might I suggest that?
Thanks, -william

I dont know that i asked my sysadmin if connection persistent are. It would like to use mysql a minimum only, but it seems so not. Thnx for your replay.

I've never seen that work. Especially with Apache and forking/preforking. I've read a ton of articles where people claim that you save some CPU cycles by using it but I have no idea if that actually works (yet/now).
I dont know that i asked my sysadmin if connection persistent are. It would like to use mysql a minimum only, but it seems so not. Thnx for your replay.
Check config/db.inc.php and check $rcmail_config['db_persistent']
If it is set to TRUE, please set it to FALSE and try again.
Also, as others have stated - the default timeout for mysql connections is 8 hrs. This is not really a problem (shouldn't be anyway), but tell your system administrator to read up on wait_timeout (or something like that) to decrease the setting. Then idle connections will no longer stay around for so long.

Since the majority of users comes with Apache/PHP combos, we should probably disable this by default. I actually couldn't believe it is set to TRUE. If someone has any objections, please raise them. Otherwise I'll make the change in the coming days. ;-)
(Note: You will still be able to use persistant connections (by configuring it to TRUE), but the default will change to FALSE.)

I know that most users will choose MySQL. I personally prefer PostgreSQL. Is there any info about users that choose the SQLite backend ? Anyone on the devel list use it, or test with it ?

Thnx all for your post, i disabeled persistant in config/db.inc.php (thnx Till for suggestion) and i asked my sysadmin if there are any problem, he replayed that now proces dont hang on,and that MYSQL5 is working just fine withot to much usage..
Thnx
Me vote to disable it from default, ALSO CACHE should be disabeled by default, as many ppl run imap on same server where the webmail is hosted, well almost.

Thanks for this tip! I had this incorrectly set and after changing it, I definitely noticed a speed increase. I bet a lot of people have this incorrectly set.

It was enabled by default, so I disabled it. It will be fixed in the next release. :)
Thanks for the heads up!
