Hi Samay,
Thanks, I'll check these things out tommorrow and get back to you. The
way I compared it was be doing a simple file copy operation (to and from the
server). I copied 30GB of data from the server to my PC.
The Server has a SCSI Hard drive and my PC has serial ATA. I'll let you
know the config and hopefully you'll find something I missed (I really hope
so, it would make my day!) . I just want
to be able to prove that it is not an SVN issue but rather a limitation of
the machines. Thanks again, and I'll be sending the details tommorow.
Regards,
Ahmed
