Hi,
On my dbench runs I've noted a slowdown between pre4 and pre8 with 48 threads. (128MB, 2 CPU's machine)
pre4: Throughput 7.05841 MB/sec (NB=8.82301 MB/sec 70.5841 MBit/sec) 70.94user 232.54system 15:17.39elapsed 33%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (1277major+1586minor)pagefaults 0swaps
pre8: Throughput 6.11383 MB/sec (NB=7.64229 MB/sec 61.1383 MBit/sec) 70.67user 184.18system 17:38.98elapsed 24%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (1277major+1586minor)pagefaults 0swaps
There have been no VM changes between pre4 and pre8.
Jens, can be the -blk patch the reason for the slowdown I'm seeing?
