First request slow

Question

I have been running weblogic on a development machine for some time now, and
recently we have gotten a server, and started to test on that
The server has a faster CPU, and more memory, and so we give the server a
larger heap size, naturally this speeds up most requests by a great deal,
but we have noticed that the first request to a page, whether it goes to a
servlet, or just returns a HTML/JavaScript page (we may move the static
pages to a more appropriate server at a later date, but anyway), is
significantly slower on the server than on the development PC.
The only different in how weblogic is run is that on the server it has 256M
heap size, whereas it has 32M on the development machine,a nd the
connectionpools are several times the size on the server.
Does anyone have any idea of why this might be? or is this likely to be
something application specific?

Answer 1

This is probably what we will do, I was just wondering if we had done
something obviously 'duh'.
And that is a simple yet effective plan, I wish that I had thought of it,
thanks.

You may wish to consider a tool that 'warms-up' WLS by hitting all
the pages.
The simplest would be a page with all URLs on them - just click
on each one.

The server is also a PC, running the same version of windows
(NT 4). I'll
have a look at the jar thing, and, yes, it is just a nuisance
(unfortunately
it's the sort of thing that crops up most often when demoing
a page to
management or clients)

And the server is... not a PC? What then?
First requests are slow because the JVM needs to loadthe classes
from disk the first time. If you deploy your applicationin a
jar file rather than in a serverclasses directory, itmight be
a little faster. It sounds like more of a nuisance thana serious
problem.
