Some new information with regard to the customer boxes that are having
problems with Tomcat performance.
Some years ago, I wrote a simple CL program and command I call
"DELTREE," that's essentially a CL front-end for the QShell "rm"
command. It does exactly what it sounds like: after presenting a
confirmation screen that requires the user to type a "Y" and press
<ENTER>, it does a recursive removal of a specified IFS directory and
everything in it.
To remove an entire instance of our webapp with this DELTREE command
takes four minutes on a box with the performance issue (an MMB with over
900G in the system ASP, and a ridiculously high CPW rating).
To remove that same webapp with DELTREE on several other smaller boxes
with much lower CPW ratings (e.g., an E4D, a 41A) takes about 5-8 SECONDS.
Anybody know why this could be?
