I just got a new Mac Pro in - yahoooo. Its a 6 core machine with 32 Gigs of RAM and 1 TB storage. The current system is running a Mac Mini from 2013 attached to a Promise RAID (Pegasus R4) and the live databases are on the RAID. Both systems are Mac OS X Mavericks server running FileMaker Server 13. The initial test of a large SQL sum returned an answer on the Mac Pro returned an answer in 2950 miliseconds and on the Mac Mini it was 4500 miliseconds. Running the test several times on each machines improved the results a lot and both machines got to where they were returning the same answer in about 3000 miliseconds. So for my first test, a SQL sum, the Mac Pro for an individual process is at best about 25% faster. I'll do some more testing, but always interesting to compare.
