My new favorit virtual machine

April 1st, 2010 events.mi, university, virtual machine

Yesterday I got access to a newly created virtual machine I can use for my streaming project. Initially I had doubts about the performance of the VM because ffmpeg2theora is encoding a DV stream there.

However after a look at htop these doubts vanished instantly:

Full 8 cores at my disposal. All with a load of 0.0% and one at 0.7%. — A screenshot of `htop` on the new virtual machine.

This is simply the best VM I ever had. I have never seen a CPU load of nan before… 🙂

Yeah, that's the Cluster that all VMs run on.
A pretty nice thing to have 🙂
Now let's hope the theora guys have optimized for multicore 🙂

Unfortunately ffmpeg2theora only works single threaded right now. However one core is sufficient to encode the stream (at 80% to 90% load). This has it's limits but will do the job.

However I'm curious how fast the x264 encoder will be with 8 threads. 🙂 It's used to encode the high quality versions at night.
