Multiprocessing in AE
I decided to test the new feature in CS3 and to see what’s the difference without using multiprocessing and with it.I took something “heavy” and sent it to the Render Queue (I used the Galaxy project which can be found here)
First I tried with the option disabled and the result was 2min26s for a frame,then i enabled multiprocessing and tried again – the result 2min28s.I’m running AE CS3 on AMD 4600+ Core Duo x64 and 2GB of RAM,Windows XP 32bit.
The question is why is the result like that?

when you enabled ‘render multiple frames simultaneously’, how many ‘additional processors’ did ae say it would use (the text below the settings will state this)?
with 2gb of ram and default cache settings, my guess is zero… to gain the extra core, try lowering the max ram cache setting to a percent that will give you between 512mg and 1gb of ram per core (you did say you had 2 cores, right). the minimum is about 512mb per core, but 1gb is recommended.
see if that helps your multiprocessing benchmark.

also note, that some effects within ae are multithreaded and will take advantage of the extra processors without having the the ‘render multiple frames simultaneously’ option on.
so, if the comp you are testing uses mostly effects that are multithreaded, you won’t see as big of gains from multiprocessing as you may on a more normal comp…
just an fyi…

After setting the Max Ram Cache there is a difference.I’m really gratefull for the help.

Thanks for reminding me about this.. messed with my cache settings as well and got the 2nd core up and running 🙂
a heavy 3d layer animation which usually took 7.5 minutes took me about 4.25
VERY happy with the results 🙂
