samba - Aug 2007 - Extremely slow file serving

Shane,

Please see my Bug nr 488:
https://bugzilla.samba.org/show_bug.cgi?id=4889
I've experienced a few strange things I can't explain.

Does the copy go faster when you access an other (random) file on  
your share?
are you able to do make a copy from a share with the client in a  
vmware session on the same samba server?

Regards,
Gaston

Hi Shane,

Yes, It's hard to imagine that 2 copy's at the same time from the  
same share transfer faster than one copy. It's the world upside-down
Funny  you mention that you also switched to 64bits. I think the  
problem started somewhere my move from 32->64 bits.


I've got a few steps I want to make:

I'm going to set-up my configuration in a vmware environment, and  
check if the clients still got slow performance.
As the whole system is being emulated, and the old configuration did  
work before, I think this is a small work-arround for me.

Next to this I'm going to see if I can install samba from scratch on  
debian.
I run Debian stable. Debian has his own packaged and I don't want to  
mess with the global setup of the debian packages.
I don't think that the installation will be hard, but  
uninstalling....I'm not sure.

Do you, or anybody else know a few test-cases, or debugs to look at?

Regards,
Gaston Bougie
