Xshell connecting too slow

Hi Guys,

Not sure if it is the most appropriate place for this type of question.

Facing a strange issue:

While ssh'ing a server (HP Ux Itanium) through putty, it works perfectly ok. But if connecting through XShell (using ssh) it takes 4-5 minutes. Traced user authentication process in XShell and following is the output.

Code:
Connecting to x.y.z.w:22...

In Putty it takes only a few seconds.

Any clues what could be wrong ?

Thanks

sending the password involves some intense computations. I've seen it take a minute or two on a Pentium II computer.

which would suggest to me that the server you're running Xshell is on is either old, overbusy, or both..
