It is also possible to reproduce the
problem with sysbench: # aptitude install 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). - Dietmar |
