Hello,
There are some differences if you hadle sessions via IPC, FS or DB. The
first
one is possibly the fastest, as everything is in memory. FS is a bit slower
(uses the
harddisk) and DB is the slowest (but I suppose that it has any benefits over
the other
two ;) , but both allow you to maintain session states if your server goes
down, allowing
me to set it in a HA cluster.
Regards,
