We're running a clustered installation of Roundcube for well over 300,000 users and database load has never been an issue for us - so it seems unlikely to me that sessions are the cause of the problem. Do you have message caching enabled by any chance? If so, I strongly suggest you disable it
you still do not get it
the argumentation was "sessions in the db are much faster" where did i say that i have a performance problem? i only said *they are not faster* in small environments they are useless overhead they are making things much more complex they are making problems you otherwise not have (Suhosin currently) ___________________
in my job i optimize any piece of software
and that is why i drive 600 CMS domains on a host with a average generate time of 0.007 seconds for a page from load index.php until the complete page is ready and have a CPU load of 2%
guess why this values are possible: because *ANY* overhead is eliminated and except RC and phpMyAdmin there is no 3rd party software involved and *any* server relevant binary is maintained in own repos and optimized for the CPU
