Hello all. Let me qualify my question by saying that I am struggling with how to ask the question I am semi green but have no issue reading up if pointed in the right direction. Please be gentle!
A RHEL server 6.2. Hosts a statistical application that has some web apps and batch programming interface.
Problem:
Lately we moved offices.
1) Now logging in via PuTTy via ssh was taking long so a poweruser set useDNS No that speed up login
2) Issue: Once we start our application (web app) login speed is fine but any action that requires a response such as navigating, open file, it hour clocks and either ends in error, or in some cases after 5 minutes renders back the requested item.
- RAM is 65 GB, 45GB is free (from Top)
- Load at most 1.35 usually around .5 avg.
- Dedicated to host one application
- At most 2-3 concurrent sessions expected but see only 1
- tracert was 1ms
- Ping replies w/o data loss
- Putty session -ssh- connects in seconds
I have run some commands and their output are listed below
[rsas@lazer ~]$ host -t a lazer.aii-3.com

I am not sure how to proceed. Any guidance/insight is deeply appreciated.
