Why is servlet slow on first access?

[Marcus Leon]

We're running on Weblogic. The first request always takes a few
seconds longer than all following requests. Does anyone know why?

We pre-compile our JSPs so it's not JSP compilation time.

These servlets do data access - does it have something to do with the
DB caching data for subsequent requests?

Or is it due to the classloader having to load some classes for the
first time?

Thanks

Possibly the database connection being re-used in subsequent requests,
if you have that feature enabled.

Class loaders, JIT compiler, jar files reads, xml configuration
files to parse, db connections, session replication.
