I never tried pscp, but I used to have incredible slowness using WinSCP
around my LAN. In the end I just made Samba work and forgot about it...

I don't remember it being asynchronosly slow, mind you... I always
blamed it on hard disk access speed on my windows box.

Have you tried in sftp mode as well as scp? There's also a commercial
product SecureFTP, from the people who make SecureCRT, which you can
try for comparison.

For LAN-based stuff though, I prefer FTP since my machines are slow
enough that ftp _has_ a speed advantage compared to scp, but I can
still move megabits/s using scp linux->linux when I do it.
