AGK slooooooow... why?

[strongbad]

im wondering why autogk is so slow for me? my computer is a p4 3.2 HT, 1gb ram 800mhz FSB. it takes nearly 3 hours to encode a 700MB file. It took exactly 2 hour 51 minute 38 seconds. the movie I ripped was 1 hour 32 minutes.

About 2x runtime is about what I get too with a P4 3.0HT 1GB RAM 800MHz when going to XVID with AUtoGK. Seems normal to me.

If you ran 2-pass encoding, and converted the audio to MP3, your times aren't out of line. In addition, the higher the resolution (i. e., the greater the number of pixels being encoded), the longer it takes. Also, if any filters were added (IVTC, for example) they will also slow the encoding. However, without the log as evidence, your statements don't really mean very much.

OK so I ran a test on two different computers.

Desktop Specs - P4 3.02 HT - 1GB PC4200 DDR

Notebook Specs - P4 3.02 HT - 1GB PC2700 DDR

I did the test on both these machines using the same settings with minimal multitasking.(Just surfing the web). Here is the log for the desktop results, I don't have the notebook log here. The notebook took about 2 hours and some minutes to complete while the desktop only 41 minutes.

That job didn't look to me to be too far out of line. Even though it was at a pretty low resolution, you got decent speed. My guess is that it didn't look too good though. The compression test percentage was pretty low. It needed a much larger file size. Even though the video was a short one (50 minutes or so), it looks to me like it could have used a full CD. Must not have compressed very well.

Yes, around what figures I get too. What was your expectations?

Your notebook may have throttled back the CPU because it was overheating.
