samba tuning on a server with > 1 GB mem.Suggestions ?? + 2.2 .2 problems

[David Brodbeck]

It seems to me the best course might be to let Linux handle the memory.
It'll devote a big chunk of it to disk cache, which will probably do more
for performance than anything you could tweak on Samba.

I'm not too worried about Samba tuning myself, since our server bottlenecks
at the 100baseT full-duplex ethernet connection it's on -- it can easily
saturate the bandwidth.  If we switch to gigabit ethernet in the future I
may have to do some tuning, though.

Hi,all

Does anyone have experience on how to tune on a server with lots of 
memory ? I'm upgrading one of our servers as mem is do cheap at the 
moment and I'd like samba to be able to utilize that.Any pointers on 
parameters to tweak ? First upgrade will be 1280 MB mem next step might 
be 2 GB depending on the performance gain (if noticable).It's not that 
the machine is slow or anything I'd just like it to be even faster :-)

Specs:

Dell Poweredge 2550
1 GHz P3
1280 MB mem
Intel Etherexpress Pro 10/100 NIC
Internal AACRAID controller with two 18 GB 1000 rpm drives in raid mirror
External PERC 3/DC Megaraid controller with two raid 5 arrays consisting 
of 6 36 GB 1000 rpm drives in each
Debian 2.2 with kernel 2.4 updated packages
kernel 2.4.13-ac5
samba 2.0.10


reason for 2.0.10 and not 2.2.x samba is that I experienced problems 
with stabilty running 2.2 during my netbench tests.No problems at all 
with 2.0.10..Anyone had similar experiences ?? It just performed slow 
and consumed lots of memory hogging the machine completely..

best regards

Christian
