i find this very vague and thus difficult to believe. a few questions:
--what kind of loads did you friend employ? what types of queries? static
content? dynamic content?
--did he use any other os than windows? oops, forgot, asp won't run anywhere
else.
--what are the precise specs of the test machines? i/o, ram, disk, etc.
--was any tuning done on either environment? ram alloc, etc.
--what jvm did he use?
--which allaire product was used? were any other products tested? there can
be a wide disparity in performance..
--was the allaire product run standalone, or was it plugged in to iis or
apache?
--are you saying that asp produced twice the output (however defined) on 2
procs? 4x on 4 procs? are you quite certain?
--did this test involve concurrent requests? what happened at 10 requests
per second? 50? 100? 500?
--was a database involved? if so, which one, and which driver, and how were
the connections implemented?
for a real test of jsp/servlet scalability look here:
http://www.orionserver.com -- go to 'benchmarks'
and remember, speed isn't everything. bear these advantages of the java
world in mind:
--choice (os, app server, jvm, etc.)
--scalability from static sites to enterprise apps
(jsp/servlets->javabeans->EJB)
--oo capability (don't try this with vb/vbscript)
--open standards, open implementations

>my friend did a performance study on smp scalability of jsp vs asp. it
>turned out that asp scaled up linearly from 1 to 4 cpus while jsp did not.
>the following platform was tested:
>- asp/iis/w2k advanced server
>- jsp/allaire/w2k advanced server
>
>tks for any info.
