Re: TortoiseCVS inside SAMBA network share

Arthur,

We've got performance issues with the client (since I've tried using cvs
clients inside *nix machines and they're quite fast when doing checkouts), I
think it's the fact of CVSNT using another process in order to connect,
retrieve, and such (that would be plink maybe?).
In our Windows machines lasts approximately 8 times longer than a checkout
from a linux machine, even being in the same subnet.
Let me show you a sample test I've made, with the following scenario:

- A CVS daemon  @ the server called cvsserverA
- A SAMBA server and a CVS client @ a machine called cvsclientA (which runs
Linux)
- A Windows XP client machine which will be called cvswindows
- Doing the checkout from the machine cvsclientA, providing it in the SAMBA,
and copying to the cvswindows local folders takes LESS time than doing the
checkout directly from the cvswindows machines.
Which means that all the process that I do using the Linux machine
(checkout, copy to the samba folder and then copy from the samba folder to
the Windows machine) is 2-3x times FASTER than using the CVSNT.exe with
TortoiseCVS from the Windows machines.

Yes, my TortoiseCVS is the latest version with the latest binaries
distributed with it (including CVSNT)

So, any ideas?

Regards,
Marcus Diniz
