One of those 2.96 compilers snuck in (my poor use of autocomplete). I take back all the previous data and submit accurate ones, and apologise profusely for ruining the signal to noise ratio on this list To rehash what the last results were _supposed_ to be and what these are. I have identical config 2.5.38 kernels compiled with either gcc2.95.3 or gcc3.2. Then I run these two kernels through a contest benchmark (http://contest.kolivas.net) using ONLY gcc2.95.3 to run the benchmark. Kernel Time CPU NoLoad: 2.5.38 68.25 99% 2.5.38-gcc32 67.28 99% Process Load: 2.5.38 71.60 95% 2.5.38-gcc32 70.86 94% IO Half Load: 2.5.38 81.26 90% 2.5.38-gcc32 88.11 82% IO Full Load: 2.5.38 170.21 42% 2.5.38-gcc32 230.77 30% Mem Load: 2.5.38 104.22 70% 2.5.38-gcc32 104.97 70% This time only the IO loads showed a statistically significant difference.
