[mythtv-users] Planning Tuners and Disk I/O for a MythTVBackend System

[Josh White]

My backend has 2GB and rarely uses any swap. It's also running other
processes. So you might be able to get away without swap, I generally put it
in anyway though. If a process needs to use it, it generally doesn't just it
long.

I have a backend/frontend running Ubuntu 9.10, and the response of the
system would get quite sluggish after running a while.  I found ghat setting
"swappiness = 0" made a major difference (google "swappiness" for
specifics).  Now my backend never uses swap unless it absolutly needs to.
 My machine has 4GB of ram, so your results may vary.  My machine generally
uses 1.8gb of ram for programs, and the rest for cache (I only have 3.6gb of
my 4.0gb available; my onboard video uses the rest)

Good luck
