Cache Tile Size Is Critical

ThunderBay 4, up to 32TB!

Photoshop CS5 ships with its Cache Tile Size default set to 128K.  That is not a Good Thing for most users.

Photoshop CS5 with OpenGL enabled compared to OpenGL disabled
Best performance for images.

Best performance is with 1028K cache tile size.  There might be some workloads for which 128K tiles are faster, but certainly not for the photography I do.

Testing cache tile size performance

The graph below shows the results on both the 6-core and 12-core Mac Pro, using the four Cache Tile Sizes.  All results after a warmup, so these represent best-case performance on the diglloydMedium benchmark.  

Behavior is consistent between the 6-core and 12-core, but relatively worse for the 12-core Mac Pro. Note how much more poorly the 12-core performs than the 6-core, see the details.
