[Seaside] Concurrent requests from multiple sessions

Hi all,

Currently we are developing a web application in Seaside, and it is
necessary for us to work in VAST. The application runs as a Windows service,
and for a few days we are facing the following issue:

- At one moment there are two users (let's call them 'A' and 'B') logged in
in the application, so we have two different sessions.
- 'A' requests a page with a long list of objects obtained from DB2, so it
takes a number of seconds to get the results.
- Less than one second after 'A''s request, 'B' requests another page, for
instance an easy static page.
- For the time the 'A''s request is handled, the 'B''s browser window
freezes and waits for those number of seconds mentioned above.

We searched really a lot, but still the results are not what we would
expect. This issue makes as confused, because in the future the application
should serve hundreds of users with very similar combinations of requests.

We didn't know, where our problem lies, so we tried a similar test with a
single page with a difficult calculation inside. Then we tried the same in
Pharo to exclude the problem in VAST. Both with the same results.

Is there anything we are missing? What should we do to achieve a parallel
(or kinda better) processing of requests?

Thank you very much for your responses.
