Rendering in After Effects way too long

Question

Hello together!I have a problem with rendering in After Effects CS6. The render times take way too much time.My clip is 2 min long and for full HD my pc needs 3 days! This makes me perplex.I already checked following points:- I'm using 13 of 16 GB of my RAM only for After Effects (less is not possible)- I enabled that multiple frames are getting rendered at the same time- also the disk-cache is enabled but I don't have a second hard drive or ssd- I cleaned the image cage memory- I disabled showing preview window with the caps lock key- no other applications or programs are running- I updated After Effects and my graphic cardThe clip is using some particle effects and masks but I can't really believe that this will cause so much render time.If someone has another idea I could try, I would be very happy.Many thanks in advance! CheersCaro

You could benchmark your machine against others by downloading one of a handful of test render files available online.

This one is pretty good: After Effects Performance Test File on Vimeo

My 2013 Mac Pro (8-core) does it in just under 7 minutes while my 2010 iMac takes just under 18 minutes and my 2015 MacBook Air does in 22 minutes.

In general, faster computer yields a faster render.

Without actual comp details nobody can really tell you much, but I'd start by not using MP rendering and checking, whether you are not accidentally using the Raytrace 3D comp renderer. You may simply overburden your system and it has the adverse effect. You know, using multiple render instances can result in an awful lot of overhead due to files needing to be duplicated and a lot of disk and memory I/O happening just as it may cause wait cycles when frames need to be rendered in a specific sequence. Sounds to me like you have all the ingredients of a "bad render setup" for that - particel effects, rrendering to a clip file and so on. Seriously, try to not outsmart AE and disable MP rendering. I'm sure it will work wonders.
