[Samba] Samba Very Slow When Using AFS and MS Office (is this a Bug?)
Hi All,
I am having a problem with Samba that seems to be a bug. I say this
because I read the archives and they described a problem similar to mine
and were told that it was a bug in older version of Samba and the latest
version should have it fixed. I am running what is essentially a RH 7.3 on
a 1.4GHz Athon with 1GB or RAM. I compiled Samba 2.2.5 in /opt/samba-2.2.5
and am using the following smb.conf:
[global]
workgroup = FLASH1
interfaces = vmnet1
bind interfaces only = yes
log file = /var/log/samba/log.%m
[homes]
guest ok = no
read only =no
[60GB]
comment = Temporary file space
path = /60GB
read only = no
public = yes
What I am trying to do is to have Samba bind only to the internal network
device so that no one can look @ my samba share from the outside network.
vmnet1 is a VMWare vertual network.
My client is a virtual Windows 2k (sp2) with the modification to the
regestry that allows passwords to be sent in the clear as described by the
Samba documentation.
Now everything is good and fast when I try to access the 60GB share that
is a local disk. The problem is that when I try to access my home
directory things are slow and sometimes files don't showup. In particular,
when I try to access MS Office files things are very very slow. If I copy
the same file to the /60GB partition accessing it through samba is very
fast and normal.
Please note that the AFS partion is already mounted before I login to
Samba from the win2k machine so Samba should just see the files there. I
started nmbd and smbd with the -d 1 option and the log.%m file for the
win2k machine is very big but essentially full of things like:
