Hi Guys,
all in all ocfs2 is a nice piece of software and works very well. Last
week i made some benchmarks and was thinking if there is a way to make
it faster.
Here are some results perhaps someone can comment them:
XFS iSCSI target:
100MB/s block write
50MB/s block rewrite
140MB/s block read
OCFS2 iSCSI target (one node connected / two nodes connected)
75MB/s block write
24MB/s block rewrite
82MB/s block read
File Creation / Deletion:
XFS iSCSI target:
5800 files/s Seq. create
5700 files/s Seq. delete
5800 files/s Rand. create
1300 files/s Rand. delete
OCFS2 iSCSI target (only ONE node connected):
5000 files/s Seq. create
5400 files/s Seq. delete
5300 files/s Rand. create
480 files/s Rand. delete
OCFS2 iSCSI target (two or more nodes connected):
800 files/s Seq. create
5800 files/s Seq. delete
800 files/s Rand. create
480 files/s Rand. delete
I would be very happy if someone can tell me if this is normal or if
there are ways to speed this up.
All tests were made using vanilla 2.6.38.8 kernel and these mount
options noatime,data=writeback,commit=60.
