Hi list,

I have slight performance problems with horde4 which seem to be related to mysql/the preference backend. The server in question is running php 5.3.8 and neither mysql nor the imap server are running on it. So far I am using horde3 groupware edition which performs really well. 

I set up a horde4 installation and am experiencing delays when it comes to selecting a mailbox, a mail and reloading the sidebar. All of these operations take a couple of seconds which first led me to believe that this is related to the new imap library which turned out to be wrong. It seems that this is related to mysql connections- if I select php sessions as preference driver the installation is working fast.

I tried both mysql/PDO and mysql (mysqli) but the problem occurs with both of them.

Did I miss anything ? Are there any hints to speed up horde4/mysql to the speed of horde3 ?

Regards
Stephan
