Performance is not the only factor here. Did you do some tests, or you just think it's slower?
there is not much to test a disk-IO less tmpfs is faster than a MySQL DB
- no session file locking (parallel requests do not wait)
this one is really very important for Roundcube.
i doubt
RC is currently the only webapp not running sane with 100% customized environment because it does things which should not be done by the webapp and if somebody has to configure session-handlers it is the admin and nobody else PERIOD
A webmail is a sophisticated app and it just doesn't work with every "100% customized environment" PERIOD
if you change the session handler make sure that *all* params are set by the application and not only a subset and it would work
however - there is something going wrong and RC doe snot log anything useful and that RC also modifies the path to "error_log" log on machines with reporting-cronjobs for the global logfile and you have to watch it's log seperatly is also not fine
