[Samba] Performance Increase Suggestions

[Noel Kelly]

Or you could just switch the filesystems to ext2?

I believe this is just a case of changing your mount options in fstab and I
think this is what John was alluding to earlier - ext3 adds a lot of baggage
to the ext2 structure which slows it down quite considerably.  Reiser and
XFS were designed from the bottom up so make the journalling less of a
performance issue.

I guess it depends if you want to lose the journalling to gain performance?

HTH

Noel,

	I had already checked the NIC and found VERY acceptable errors.
In over 2GBs of data transferred since my last scheduled maintenance
reboot, there has only been 3 errors and 1 overrun. Which to me, is
negligible as far as errors go.

	I have a sinking suspicion, that I am none to happy about, that
I will need to compile a kernel with ReiserFS support, move ALL the data
off of the Samba share, rebuild that partition with ReiserFS, recreate
all the file permissions and then copy all of the data back over.

	This will of course take a few weeks, as I will need to run
plenty of tests on the "spare" server and I only have a few hours
available each week to work up such changes.

	Well, so much for the "quick" and simple fix.

Just a thought, but I would check for errors on your NIC with ifconfig.
Read times might still be quite good whilst write times are shot if
there
are network errors I have found.

Noel


Without spending money, are there any other methods
through which I can dramatically increase the network write performance?
