With and without kmap_atomic() -based copy_*_user() patches from akpm.
Taken on a 16x/16GB box.
Take 1: total throughput:
before:
Throughput 32.3019 MB/sec (NB=40.3774 MB/sec 323.019 MBit/sec) 512 procs
after:
Throughput 46.9837 MB/sec (NB=58.7296 MB/sec 469.837 MBit/sec) 512 procs
In the follow-ups I'll include oprofile numbers for each and vmstat logs.
Cheers,
Bill
