when reporting performance figures can you run this with again time, top can be
very deceiving. like so:

time filesrc location=blood.avi ! ffdemux_avi ! ffdec_mpeg4 ! ffmpegcolorpace !
videoscale ! fakesink silent=1

which typically gives in 0.10 (with blood.avi in bug #337866):

real    0m4.364s
user    0m3.205s
sys     0m1.051s

and in 0.8:

real    0m3.163s
user    0m2.468s
sys     0m0.660s

after that you need tools like cachgrind to figure out what's slowing stuff
down. in 0.10 it could be bug #321662.
