DM355 NEW (3.10.0.19) DVSDK Performance Issue (vs Old DVSD 1.30)...BIG problem!

Hi,

I just received a new Digital Spectrum DM355 evaluation board, and I took it for a spin...

My test setup:

• New EVM Board
• NFS Mounted (to the appropriate file system (either new or old DVSDK root file system))
• Running encode demo app (built for that system)
• Writing to usb flash drive.

My Command line looked ~this:

   "./encode -b 6000000 --v /mnt/usbFlash/test.mpeg4"

I look at performance via several metrics:

1. total Idle time
2. keeping bit rate up to configured (6Mb)
3. keeping up to 30fps

a)  Software that came with the EVM (DVSDK 1.30 (with Montavista 2.6.10) --> Old DVSDK

Results/Performance

1. 70-75% Idle (even writing to USB Flash Drive)
2. 6Mb (wavered a little, but not much)
3. (solid) 30fps.

b) Latest DVSDK release from TI (using DMAI) - DVSDK 3.10.0.19 --> NEW DVSDK

1. 0% Idle (10-15% in application, 20-27% in sys, and >50% in I/O)
2. Swung wildly @ very low bit rate (avg was  ~< 2.4Mb)
3. ~12fps

Obviously, when I tried to play back the NEW DVSDK imag there were frames missing and lots of errors.

I have compiled everything into 'release' mode (in DMAI) as well as optimized the kernel...etc

What is going on here?
