CPU load level

d3cadent · 2008-06-15, 09:13

Hi gurus and forumers,
my system is a core2duo, with a hardware mpeg2 analog tuner. I use MP 1.0 RC1.
When TVServer is recording a program in the background or is doing timeshifting (without any clients connected, so recording is done only), my CPU load jumps up to somewhere between 25% ad 50%. This, in a dual core setup means that one core is utilised to 50%-100%. Usually, watching a program is utilizing the cpu to only a marginal level - it seems rcording is the task that takes this much.

I have always been under the assumption that a hardware MPEG2 encoder is supposed to take quite some load off the CPU during recording. Do you think this high cpu is normal? What is the actual reason for such a high CPU requirement? Is there something I could do to make utilisation lower?
(well, this last question is a comfort question. In my home the room temperature during summer can go up to 25-28 degrees celsius, and in such warm environment the cpu fan starts making more noise under higher loads. I would like to make less noise for my family.)

Thx, tom

Your right cpu is way to high, mines 2-3% whilst recording\timeshifting DVB stream.

Know there have been some analogue fixes with the latest svn, might be worth trying.

Thanks, PD. For now I'd rather wait for RC2 as the problem for me is not a showstopper. I'll report back when RC2 is out.
