Avisynth and speed

[lamola2003]

I compiled one file avi-DV Type2 with CCE

With this script:
AviSource("Disney.avi")
showframenumber()

and without script

This is my result:

With script: 3 minutes 15 seconds, max speed CCE 0.52
Without script: 1 minute 51 seconds, max speed CCE 0.98

This diference is normal?
My computer is AMD XP1800+, 1HD 40GB 7200rpm (for program and s.o XP-Prof, 1HD 120GB 7200rpm (for data only), 1GB RAM DDR266.

Thank in advance.

You are making a very unfair comparison here. Actually showframenumber() is a remarkably slow filter. Now, if the avi is encoded with a fast codec like huffyuv or mjpeg, then the above result are very understandable. Thus if you really want a comparison, do it without showframenumber().
