Why TC 5.5 vs TC4.1 (perf reasons)

[Leon Rosenberg <rosenberg.leon (at) googlemail.com>]

well we documented it in wiki, which is of course not public, but i
can attach some tables from there:

Tomcat 4	lime	30-40
Resin 3.0.5	lime	34-35
Tomcat 5	lime	40
Resin 3.0.7	lime	43-45

Since it's more then 2 years old the test scripts aren't available
anymore, so it's hard to repeat the same test, but you could write a
test for yourself, couldn't you?

The test included sending a request which forced the app to perform
some operation on disk and return a jsp back.
Btw, the page was very 'basic' at the start, with 'well html designed
and layouted' pages the results started to move in favor of tomcat 5
against resin.
