I have 2 computers (Linux with attached RAID) and Win2000 Pro connected directly using CAT5 crossover cable. Transferring a lot of data from Win2000 to the Linux (to the RAID) using WinSCP and the speed is about 1.6 Mb/s ... why is it so slow? Can it be faster? Both NICs are 10/100 :-/

thanks,
S

forgot to mention that is on TCPIP and I'm using real IP addresses rather then 10.0.0.1 or sommething. Can that be the problem? those computers are only connected to each other and there's nothing else connected to them.

Ip addressing will have no bearing on transfer speed.

Besides which...10.0.0.1 is a real IP address (not sure what you meant by that but I'd wager you don't really understand IP addressing that well from the above statement)

It's entirely possible one of your NIC's is set to only transfer at 10 mbps. Just because they're rated for 10/100 doesn't mean they will actually transfer at 10 or 100 mbps....in fact....on average it's been my experience a 10 mbps connection will transfer around 5 or so. I think you should do some reading on setting up your NIC's for optimum transfer rate....something is likely not set properly on one, the other, or both NIC's.

you should set the nic manually on both computers for 100mbps and full duplex. I believe it usually defaults to 10mbps and half duplex? Half duplex meaning they take turns talking...while with full duplex, they talk at the same time

Remember that it can be confusing that to find MegaBYTE's per second you have to divide MegeBITS by 8 which will get you megabytes per second.

So 10 megabit would be approx 1.25 megabytes right?

and 100 megabit would be 12.5 megabytes per second

which - in theory - means that there may be a hardware issue somewhere, because the connection is running faster than a 10Mb line, but slower than a 100 ... Check your cables, and make sure that the cards are in good order

:$ umm regarding that last post ... a full duplex 10Mb/s network transfers files faster than 1.25MB i think ... nearly double because they can both talk at one time ... sorry for the confusion
