Hi all, we observe very slow fsync rates on newer 2.6.32 kernel with OpenVZ:
It is possible to reproduce the problem with sysbench: # sysbench --test=fileio --file-num=1 --file-total-size=50G --file-fsync-all=on --file-test-mode=seqrewr --max-time=100 --file-block-size=4096 --max-requests=0 run Requests/sec executed is considerable slower on OpenVZ kernel (factor 20 on Intel Modular Server). Can someone reproduce that problem? - Dietmar
