Hello Brian,
The 95-110% in top means 95% of one processor to 100% of one processor plus 10% of another. If it said 2400% it would be using all of the 24 cores in the worker. I like htop better than top as it has a usage bar for each core and is easier to use (IMO). Like others have said not all codecs will use all the threads when encoding, but most will if configured properly. Or if left alone you could have 24 concurrent processes going and they would all be just as fast as the one which is good if there are a lot of classes scheduled around the same time. All the best, Luke From: [email protected] [mailto:[email protected]] On Behalf Of Brian Bolt Sent: Thursday, December 30, 2010 10:55 PM To: Matterhorn Users Subject: [Matterhorn-users] Ramping up production 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.

Thoughts and ideas are greatly appreciated. Thanks, Brian
