My backend system (Athlon XP 1700+) registers a processor load of about 0.6-0.7 when backend is idle (ie no streaming, no recording going on).
Seems high. Granted I am running my backend on a P4 2.4, but my load ave is 0.00 when idle (just now checked it to make sure).
The top command indicates that virtually all this load is from the myth backend processes.
I have never really understood what is a "good" load average, but I thought it was generally best to stay below 1. So this seems a high idle load.
Best to stay below 1.0 per CPU. For example, on a dual processor system this should be below 2. Not that this is hyper-critical. The load average is the number of processes that are in the run queue. Basically the number of processes that could be running right now if they had CPU. The higher the number the more things want to run at the same time, blah-blah-blah. Anyway hopefully you get the idea. There is more to it than this, but hopefully this will give you the idea.
So the question is, what on earth is the backend amusing itself with all the time?
Good question. I just started something to record to see what would happen and my load avg only went up to 0.07. This is on Fedora Core 2 with 2.6.11.2 kernel, (2) PVR-250 (ivtv 0.2.0 rc3h), P4 2.4GHz as mentioned above, 512Meg RAM, 6 ATA hard drives (4 in LVM with XFS).
