First export test in CC, Very Slow

Question

So, I made a test with a 1:30 min. sequence.
In CS6 the export time is 00:03:52
In CC: 27:43!!!!!
Exactly the same sequence, same export settings, both via Media Encoder CS6 & CC respectly.
What could be the problem?

Answer 1

I ran some more tests.  Here's what I have so far:
Windows 8 Pro 64 bit
i7 2500
8GB DDR3 1333 RAM
1TB HD (single drive)
GTX 560 Ti 2GB, 320.18 driver
CUDA acceleration turned on in both versions
I imported a 4 minute AVCHD clip with a lot of action.  I created a sequence based on that clip.  I exported that clip with no edits or effects to BD and DVD settings identical in both versions.
Using AME for Export:
CC7_BD = 5:58
CS6_BD = 5:43  <---Winer CS6
CC7_DVD = 3:07  <---Winner CC7
CS6_DVD = 3:12
Using Direct Export
CC7_BD = 5:49
CS6_BD = 5:40  <---Winner CS6
CC7_DVD = 1:39  <---Winner CC7
CS6_DVD = 2:55
So, it looks like MPEG2 is faster with CC7 and H.264 is faster using CS6.  The biggest difference is for DVD using CC7.  Look at the times for AME and Direct, nearly cut in half!
Now it should be noted that a brand new project was started in each version.  I've seen reports of older projects opened in CC7 behaving slowly, so I wanted to take that into account.  And in fact my first test was done opening an older project, Harm's 5.5 benchmark project, in fact.  So far, it's looking like where the project was created makes a difference.  Of course, Harm's project was full of effects, and this round of tests used none at all.  That's the next step, repeating these tests with effects, both accelerated and not.
