[Freeswitch-users] Will sqllite on a ramdisk be more performant than postgres with the db on a ramdisk?

I've got a piece of tech that I'm working on where I don't really need to worry all that much about recreating the FS DB on a reboot. With that in mind, I'm thinking about one of two options: 1) Sqllite on a ramdisk. 2) Postgres with the db for FS placed on a ramdisk. What do you think I will get higher performance out of?
