Compared to i386 how much memory is PostgreSQL and other apps using? On another thread I asked about memory usage was told that apps in AMD64 mode seemed to be taking twice as much memory. I would be very interesting in reading about PostgreSQL memory usage in FreeBSD AMD64. > For normal regular server usage, though, I don't see a need for opteron. I wonder other data intensive apps (ie image/audio editing) how they would do in Fbsd-AMD64. Also I wonder if it's an advantage only when large amounts of data are moving or lots of data in general. For example a busy news server or email server.
