UNIX for Advanced & Expert Users

Hi every one,

We have HP UX server which normally loaded as avg load of 19-21.

NOw when I try and do ftp to this server it takes ages to get the FTP prompt.

I have seen this server loaded as max agv load of 35-40 tht time we never had such problems of FTP sessions.

Now my new Unix admin says the load on the box is very high that is why it is taking time to do the ftp;however I dont not agree with this as it was working from the day I am wokring in the project.

Now when the avg load is brought down to 2-5 FTP processes are woring fine.

Can any one tell me what exactly may be going wrong?

Cheers,
Nil

What you seem to have is an "observation", not necessarily all the data that impact ftp. These are some (not all ) of those factors:

1. Network traffic load/congestion
2. I/O wait queues - this has a high probability of being a culprit
3. CPU queue length
4. Changes in network/system configuration

Do you know that all these factors were the same when things worked really well?
Have there been changes to the network - like a new router?
Has the sysadmin tinkered with the ftpd config file?
Are there background jobs that are I/O intensive, like maybe you went "live" for some part of a system.
