Bill, I did limit the build to C/C++ and the testsuite only. In case you are interested, I did the build on my HP xw8000, which has dual Xeon 3GHz CPUs, 3.4 GB RAM, and 10K rpm hard disks. However, I did not use the SMP "make -j 2 bootstrap" option and I limited the RAM available to cygwin to 1GB (The upper limit for cygwin is 1.5GB). Nonetheless, during the build both CPUs were pretty busy at 60%-80% and RAM usage hovered around 800MB. Next time I'll up the memory limit to the max and also monitor virtual memory size and page faults. Since both CPUs were pretty busy I doubt that the -j switch would change much.

I'm jealous. :) At about 2:00 AM, I told my Sunblade 100 workstation Tamino to build gcc-4.2.0. Instantly, he began to clink, to clank, and to clunk, and stopped "drumming" at about 9:45 PM that night. Some guys get all the luck. ;) Bill
