I am running a Fedora 2 machine with Samba 3.0.7. I am using LDAP to
store the user info. Everything is from stock rpms. I am using domain
logins for my users.
Since 3.0.6, whenever someone tries to write a file to the server, it is
extremely slow. It doesn't matter whether it's a Win XP sp1, sp2 or
Win2000 client but for some reason, my computer didn't have this problem.
What I found out is that I had done the registry "tweak" from
speedguide.net. Once I applied this registry edit, it worked on other
machines too.
Here is the contents of their registry file:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SackOpts"=dword:00000001
"TcpWindowSize"=dword:0003ebc0
"Tcp1323Opts"=dword:00000001
"DefaultTTL"=dword:00000040
"EnablePMTUBHDetect"=dword:00000000
"EnablePMTUDiscovery"=dword:00000001
"GlobalMaxTcpWindowSize"=dword:0003ebc0
I am not sure which line of this fixed the problem but I am sure that
someone would could tell from looking at it. I am wondering what would
have changed between 3.0.5 and 3.06 to have done this?
Also, I am running an almost exact replica of the problematic server on
another machine and I it works fine without any modifications to the
client's registry.
Thanks,
Doug
