Ok, I have AMD 64 X2 Dual Core 4600+ for processor. I made melt a xml
file using RGBNoise as filter, and rendered 375 frames of PAL.

WITH THREADS:
-------------------------
Command: melt /home/janne/rgbnoise.xml -consumer
avformat:rgbrender_threads.mpg real_time=-2
Render time: 2m44s
top CPU usage: 130 - 134%


WITHOUT THREADS
-------------------------------
Command: melt /home/janne/rgbnoise.xml -consumer
avformat:rgbrender_no_thread.mpg
Render time 1m47s
top CPU Usage: 98 - 100%

So it seems that old dual core processor works faster with single
thread, even though 'top' gives higher CPU utilization for
real_time=-2.
