samba - Sep 2002 - Slow browsing windows shares from linux/samba

Hello all

I have been searching around the internet and even used the searchable
samaba mailing list archive. It seems I have a rare case of where my problem
is reversed to the common slow samba problem.

My problem is this:

I have a network of 3 PCs, one Linux 2 Windows XP. They are connected via a
hardware router (switched) on the 190.190.1.0 network. On the linuxbox I
have a collection of files that I want to access via the Windows PCs. This
works fine, even fast (thanks to socket options).

But now, if I want to browse the Windows PCs from Linux it takes ages to do
so. I can get the listing of available shares via Linneighborhood real
quick. Mounting works flawlessy. Then I open the mountpoint and it takes
between 30secs to 4 minutes to open the share and display its contents. I
noticed that if I am very fast and have a filebrowser ready, that after
mounting the share I can browse at realtime speed for about 2 secs. After
that the above behavior takes place, and even a directorylisting for a share
with only 2 files takes 30 secs. This is true for both Windows XP PCs.

Why does it work fine in the direction Windows->Linux but is horribly slow
from Linux->Windows?


Any help would be appreciated.


Here is my smb.conf:

Well I got it. And I have to apologize for my own stupidity.

First off:
 SO_SNDBUF 8192

Well, if you miss the "=" in it, it cannot work.

Doing that fixed my browsing issue. But I was back to 80 mins copy time for
a 600 MB file. So I set it to 4096 and it was reduced to less than 10 mins.
Thats how it looks like right now. Hope it doesn't change.

I learned quite a lot through this.

Guess I will stay on the list for a while and try to offer some of the
knowledge I gained to make up for spaming you =)
