Moving the ephemeral databases to a RAM disk will greatly improve performance, and it is CRITICAL to move them to a RAM disk if you use SSDs. More info on running FreeSWITCH on SSDs is here


Some Linux distros have quirks that cause SQLite to behave poorly when scaling up. (I'm talking to you, OpenSUSE!) In other cases, disk I/O just isn't up to snuff. Putting the FreeSWITCH db files into a RAM drive can increase performance.

NOTE: The voicemail db information is also stored in the RAM drive, so be sure to back that up if you plan on restarting your system.


bkw_: I suspect you need to put db on a ram drive
[3:14pm] bkw_: mkdir /ram
[3:14pm] bkw_: mount -t tmpfs tmpfs /ram
[3:14pm] bkw_: then cd /usr/local/freeswitch
[3:14pm] bkw_: mv db db.old
[3:14pm] bkw_: ln -s /ram db
[3:14pm] bkw_: then restart freeswitch
