slow web services

[BonaM]

Hi,
I'am a running web service on IIS 6.0 and asp.net 2.0. Every time the
first request to the service takes about 15 seconds to give a response.
For the next 60 seconds the response returns in about 3 seconds, but
after that 60 seconds period it takes again that 15 seconds delay to
load. This happends with every WS I have created, including the most
simple visual studio "hello world" template. Any ideas to get rid of
that limited 60 seconds period? Or to extend it?
Most of my services returns non-static data, so caching the output
response is out of the question.

Does your application use any kind of caching - it could be that you
have a cache database call (or something) that lasts for one minute.

Otherwise - are your IIS settings configured to drop your application
pools after a short time? Poke around your application pool settings in
IIS Admin.

Finally - does your application make use of a lot of threadpool threads
(probably through calling other web services or manually queuing items
on the threadpool). If so, check out this article:
