[Freeswitch-users] Performance bottleneck

[Ken Rice]

The Disk IO on sqlite can be quite a bit... One work around for this is to
create a ram drive of sufficient size and mount it to
/usr/local/freeswitch/db (or whatever your db dir is for freeswitch) this
helps out greatly... But anything in the db will not be saved across system
reboots unless you do something about that yourself

It's going to be the disk io from sqlite.  The presense states are all
stored in sqlite (or odbc) data source.
