Hi Brian,
from what I was told by our server adminstrators and what I can see in
the hobbit trend charts is that the bottleneck for a fast processing is
not the CPU load alone but also the disc access speed to the shared
medium. maybe you can have a look at this to if you want to speed up
your environment.

I have a distributed install running 1.0.1. The Admin and Engage
servers each have 16 cores (Intel). The Worker server has 24 cores
(AMD). My first one minute capture took about five minutes to
process. My second capture is an hour long, and at 1 hour into
processing it is currently encoding the presentation (screen) for
preview.
I expected that the Worker server would endure the greatest processing
load, and 'top' shows that ffmpeg is using 95 - 110% cpu. However,
when I run mpstat -P ALL, all processors are greater than 95% idle.
Based on what I saw in my VM test environment, I anticipated that a 1
hour capture would take well under 15 minutes to process.
On another note, the amount of space consumed is very large, 345 MB
for the one minute capture an 15.6 GB for the one hour capture. Note
that I don't yet have the workflow yet configured for streaming, so I
anticipate that these numbers would be even larger if streaming were
in the mix.
[r...@server matterhorn]# du -h --max-depth=1
25M ./streams
8.8G ./files
6.5G ./workspace
68K ./server1
2.5K ./inbox
78K ./searchindex
22M ./downloads
16G .
Thoughts and ideas are greatly appreciated.
Thanks,
Brian
