Well.. hmmm there's a distinct possibility your Macbook will clean the iMac's clock... as in run smoother with more tracks and FX.
Not only is Tiger more efficient than Leopard, Logic 7 is a speed demon compared to Logic 9, especially on the older machines. I still have Logic 7 on this G5 and it will run far larger projects without any problems.
Have you checked to see if preference settings, I/O buffer, and other performance related settings are the same on both machines.
More recent versions of Leopard seem to write to the system drive quite a bit, OS 10.5.7 that I'm using accesses the system drive more frequently than 10.5.5.
I put a drive use light on the Mac a couple of years ago.
Possibilities...one of the VI plugins is causing a problem, not compatible with 10.6.2, maybe a memory leak?
Spotlight keeps indexing your drive. Disable or temporarily limit it's use using preferences.
Leopard journaling is more aggressive than earlier versions, so a combination of too many drive writes/reads on the system drive?
