Hi,
I just compared 2.1.46 vs. 2.1.46+pentium memcpy patch, and interestingly enough found that the UNIX byte benchmarks tended to _drop_ a fair bit, with the exception of process creation and execl throughput. (Note that I only ran the basic 'system' tests - TCP bandwidth etc. to be determined when I find the newer benchmarks)
This is most interesting since I used to swear by the patch.
It does however show us that there still is performance to be gained. I presume the process creation test will be using fork() which does a lot of memcpy'ing of various process credentials in kernel space.
Chris
