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

The presense states are all stored in sqlite (or odbc) data source.
