processing writes requests in data=journal,sync mode
Hi,
We are currently doing SpecSFS comparison benchmarking to evaluate
advantages of FS journaling to NVRAM card versus journaling to hard disks.
We compare NFS performance for Linux file server with ext3 file system in
?data=journal? mode for three different locations of the file system
journal:
- inside main file system
- on...

ext3 performance with external log
...e benchmarking results: ext3 with internal log performs 3 times
faster then with external log.
Linux ES 3.0 (kernel 2.4.21-9.0.1ESsmp), Dell PE 2600, 2 CPU 2.4GHz, 6GB
RAM, Adaptec Ultra 160 SCSI 29160 controller
External hardware 9-disk RAID 0; 512MB write-back controller cache; U160
Benchmark: SpecSFS v 3.0
Mount options: data=journal,sync,
Export options: sync,
With ext3 FS on external 9-disk RAID 0
internal log ~ 3000 NFS Ops/sec
external log on a second partition on the same RAID 0 ~ 1000 Ops/sec
external log on a dedicated HD (without write-back cache) or NVRAM card
~ 100...

Re: [nfs-discuss] bug 6344186
......
and funny you should ask... we''re working on it right now, here''s the bug:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6344186
As for NFS on ZFS performance, that is also being actively worked on -
one bug in particular that''s holding back (at least) specSFS results is:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6350001
6350001 improves lookup performance, and should be putback very soon.
Neil has some ZIL and range lock changes coming, Matt and Noel have some
ZAP perf changes in the pipeline, and Mark''s ARC changes are goin...
