The timings below were generated on various machines using a simple benchmarking utility in slicer ([http://splweb.bwh.harvard.edu:8000/cgi-bin/develop/viewcvs.cgi/slicer2/Testing/Attic/bench.tcl?rev=1.1.2.8&content-type=text/vnd.viewcvs-markup&only_with_tag=release-2-6&cvsroot=slicer bench.tcl]). The goal was to look at performance scaling for multi-threaded processing.
 
 
 
The machines used were:
 
 
 
* localhost.localdomain: an 8 processor Opteron system with 128 Gig of RAM made available for testing by [http://www.pcsforeveryone.com PC's for Everyone]
 
* mimer.local: a 2 processor G5 PowerMac
 
* forest: a 10 processor SunFire
 
* vision: a 6 processor Sun
 
* rock: a 3.4 gigahertz pentium 4 dell XPS laptop (one processor - two thread timings use 'hyper threading')
 
* deuce: a dual processor opteron
 
* glider: a dual processor xeon (with hyperthreading to get 4 threads)
 
 
 
Times in the boxes are in seconds.
