transfer files between windows and linux

guixingyi · 01-18-2011, 08:42 PM

Hello,

I have question about transfer files between windows and linux in 1000Mbit network,

between linux servers the copy rate is 50-70MB/sec(with scp copy)
between windows servers the copy rate is 50-70MB/sec(with cifs share copy)
between linux and windows the copy rate is 8-11MB/sec(with winscp copy windows -> linux, I did not try to copy in reverse way)

I suppose that maybe it because of platform difference,
but I am not excatly sure about this,

is it possible to improve this??

I would probably put the blame on WinSCP, that is certainly the weak link in the chain.

Is there a reason you need to use SCP? Have you considered simply using CIFS through Samba?

I guess you could install microsoft's services for unix and try the tools ported for windows.

the reasons I made such experiment is because I have same issues with NBU7(netbackup 7.0 installed on linux as master and media server) for backup linux and windows in 1Gbit network,

the rate of linux backup was 30-50MB/sec, but windows was rate of 4-6MB/sec.

I don't know the network benchmarks of NBU for windows and linux,

check also the performance for pscp from putty.zip.

Try:

-> Make the gateway nearest or very shortest path to deliver the packet.

it is same, I used pcp.exe for copying files between windows and linux

so I am wondering, whether anyone has experienced this issue? any solution for this?

Make sure that your NICs are hard coded to the speed that you want them at. We had problems in an environment I was in with Netbackup and devices that were set to auto-negotiate. Once we changed the settings for the nics the speed issue went away. Just one of those odd things that was stumbled on with netbackup.
