| |
I changed the report generator for ctxbench slightly after the recent discussions of system call methods. I added a column of context loop rate divided by MHz of the processor, and ran on the same or similar 2.4 kernels (this is a hardware thing, version matters only a little).
What it showed was a piss-poor value for the P4, best for my old P-II Celeron, and Athlon vs. P-III closely swapping third place. In fact the P4 had a value about 3x slower than the P-II.
If someone wants to run the benchmark with the old and new system call setup it might be useful to quantify the gain.
Benchmark is at www.unyuug.org/benchmarks, and if someone tests this I'd like a copy of the raw results for my collection as well as the extract posted to lkml.
