Top is running with -d 1. (1 second delays)<br>
<br>
Here's a sample of the "top 10" (see below) while my wife is watching
something recorded the other night in 1080i _and_ the BE is recording
something else in HD (not sure what format) Notice that thread 13136
is running with a priority of -2. That's a realtime priority. Thread
13133 is doing something I have no clue about. Here's the fun one:
thread 6097 belongs to X and is eating 70% of a single CPU. The _only_
thing running under X on this machine is:<br>
<br>
1) fvwm<br>
2) mythfrontend<br>
<br>
That implies that mythfrontend is dumping a ton of load on X, but I
have no idea why. The FE is running at 720p resolution, BOB deint is
turned on, along with XvMC, and RTPRIO is working. Audio is being sent
to ALSA:spdif. I'm getting tons of prebuffering pauses.<br>

<pre wrap=""><!---->What is your top delay (press D while top running, or start top with -d
flag). Default is 3 seconds, so the load is averaged over a 3 second
period. I noticed this when I was testing an Athlon XP 3200, with a high
bitrate HD stream the load was only around 40-50%, peaking to 60% when
popups were being inserted. No problem, right? However, setting the
delay shorter to 1 second showed a different picture, in which the cpu
load was spiking to 100% when a popup was displayed. No doubt shortening
the period further would show more of the impact.

<pre wrap=""><!---->This is what I've noticed ... some streams I'm playing are high bit rate
(~17000 kb/s for some HD channels) and some much lower (SD or recorded
from analog are 3,000 - 5,000), and the high bitrate are somewhat of a
problem.
