Hi,
 
    Trying to understand a problem or performance that we have in our
application, we've seen some data of interest, Those files are the result of
OptimizeIt CPU profiler output - Sampler, Those files show the execution of
the same JSP and logic in three moments.(well i send a file by mail ...
cause the mailer doent accept more than 100 kb)
    
    When working with JSP we have a serious degradation problem with acces
to filesystem:
 
        - java.io.Win32FileSystem.getLastModifiedTime 
 
    There's some way to desactivate the control of changes in JSP file's?.
In order to avoid access to FileSystem.?
     
 
    Finally our problem was with Taglibs iterate ... logic ... it creates
thousands... of objects ... and the GC eats the whole machine.... but that's
an advise to other list.

Thanks for you patience and time
