Yes. The speed reported by the tools are accurate. I measured them with task manager, and confirmed by timing them.

What version of PSCP and WinSCP are you using? What protocols (note that PSCP supports also both SCP and SFTP). WinSCP should be much faster, at least for large files.

Why is winscp slower than pscp?

2005-09-22 14:26

I was under the impression that WinSCP was based on PuTTY code. If so, I do not understand why WinSCP is much slower than pscp?

I have done benchmarks using the WinSCP in console mode, and found that pscp transfers files more than twice as fast as WinSCP, using the same encryption methods.

Don't get me wrong though, speed is still acceptable, and WinSCP features makes up for it. Especially things like the synchronize command, which is soreley missing from PuTTY.
