[Samba] SOLUTION: Slow file transfers from Samba server

2006-06-05 Thread Bret Holbrook

Here was the solution to my slow file-transfer problem from Scott.  I
coincidentally did have a HP Procurve 4000m (what are the chances), ended up
swapping out the switch and presto.  I can't believe I didn't try it
before.  Thanks again Scott.

Here are some links I researched previous to this though that may help you.

Also if you google slow samba there are a plethora of discussions on it:

Good luck.

I had a similar problem in the past and the problem was I locked the NIC and
I think the switch (HP Procurve 4000M I think) at 100Mb/full. Seemed like a
good idea at the time. Changing the ifconfig to auto-config and the hub as
well resolved the issue.

This is a known documented issue with the link negotiation architecture from
what I remember. There was a HP whitepaper on it.

[Samba] Slow file transfers from Samba

2006-06-04 Thread Bret Holbrook

Scott,

That fixed the problem.  Unbelievable, I've been dealing with that problem
for almost two years.  I can't believe I didn't think to try that.  I
erroneously assumed that if you had a 100mb switch plugged into a 100mb card
you were going to get 100mb out of it.  I'm almost ashamed of myself having
been an IT Administrator/Manager for about 15 years.  Anyway, thank you very
much for taking the time to offer up a solution, you have truly made my day.


Many thanks,

Bret

[Samba] Slow file transfers from server to XP clients

2006-06-03 Thread Bret Holbrook

Hey everyone, I'm sure this topic has been discussed, but I've looked
through history and done google searches and just haven't found a resolution
yet so I'm hoping the experts can help me.

Running Fedora Core 5 and Samba ???  Not sure the version off-hand.
Clients are XP Professional

The problem is miserably slow file transfers from the server to the XP
clients (and it's primary purpose is a file server) and I mean along the
lines of 4.5 to 5 hours for a 5 gig directory.  This is over a 100mb
switched network with a really good HP managed switch.

Transferring the same directory from client to client takes less than 45
minutes.

Transferring data to a Win 98 client on the other hand moves much faster,
not as fast as win to win but acceptably fast.

I have had the same exact problem through about six generations of
Linux/samba from RedHat 9 and each version of Fedora.  Each time I have done
a complete format/re-install and same problem.

I have also tried switching the Nic in the server with a working pull from a
client and no change.  I even forced the Nic to 100 full in dos before
placing in the Linux box.

Really at an end of my knowledge which was limited in the first place, just
not sure why this isn't working and really trying to avoid putting 2k3 on
there.  Any Help would be greatly appreciated, or if the topic has been
discussed ad-nauseam then if you could post some links or point me in the
right direction that would be helpful.
