Test description:
* dd512w - write 512MB
* dd512r - read 512MB
* dd512rw - rewrite 512MB
* dd1024w - write 1024MB
* dd1024r - read 1024MB
* dd1024rw - rewrite 1024MB
* dd2048w - write 2048MB
* dd2048r - read 2048MB
* dd2048rw - rewrite 2048MB
* kernuntar - untar kernel
* kernstat - stat kernel tree
* kerncat - cat kernel tree to /dev/null
* kernrm - remove kernel tree
* kernuntar2 - 2 concurrent kernuntar
* kernstat2 - 2 concurrent kernstat
* kerncat2 - 2 concurrent kernstat
* kernrm2 - 2 concurrent kernrm
* dbench4 - dbench with 4 threads
* dbench8 - dbench with 8 threads
* dbench16 - dbench with 16 threads
* dbench32 - dbench with 32 threads
Legenda:
* REAL - how long a test took
* UTIME - how long it spent in userspace
* STIME - how long it spent in kernelspace
* READ - how many KBs were read
* WRITTEN - how many KBs were written
UTIME/STIME/READ/WRITTEN are gathered from /proc/stat
so they include all system activity (important for
delayed allocation)
Notes:
* all filesystems are mounted with noatime
* before every test, filesystem was recreated and
remounted after preparation
* reiserfs is mounted with notail option
* ext3 is mounted with reservation,data=writeback
* xfs is mounted with logbufs=8,logbsize=256k
* ext4 is mounted with extents,mballoc,delalloc
