Default Very slow transfers under AIX 5.3

Hi All,
I've got SSH/SSL (OpenSSH_4.3p2, OpenSSL 0.9.7l 28 Sep 2006)
running under AIX 5.3 (TL5, SP3). It is running on a 9112-265 with
2.5Gb RAM and runs nicely.

Logging on takes no time what so ever. Sub second.

The machine is connected to the Lan at 100Mb/s (verified from
entstat). It it connected via putty from an XP box, also at 100Mb/s.

File transfers using psftp or pscp (putty's secure ftp and cp
respectively) are running at about 20Kb/s!

The transfer via normal FTP is fine.

When the sftp/scp transfers are taking place, the CPU, network and
disk are not being overly loaded. CPU is <10%, disk is <20%.

This is driving me nuts!

Most of what I've read is about slow logons, which is not my
problem.

Anyone have any suggestions?

-Chris
