For anyone interested in new hardware...
Just took delivery of new Mac Pro Late 2013 (the trash can) basic config 3.7ghz Quad-core 12GB RAM 256GB SSD driving Thunderbolt display.
Comparing script run times to my Late 2013 Retina MBP 2.6ghz Quad-Core i7 16GB RAM 1TB SSD driving Thunderbolt display.
One test script that took 12 seconds to run on MBP, took 14 seconds on the new Mac Pro. I had hoped that the higher clockrate would improve execution speed, but in fact the 3.7 Mac Pro was measurable slower than the 2.6ghz MBP.
I know this says nothing about server tasks, or other more disk intensive duties, but for script execution, there appears to be no advantage. Tried changing cache size from default of 128 to 512 without change. The file I am testing is not huge. 170MB data file.
From other reports, I anticipate better results when I move to my FinalCut Pro X projects...but for Filemaker, it looks like the MBP still reigns supreme. Has anyone else experienced different results?
