Maurizio Cucchiara commented on OGNL-18:
----------------------------------------
During my latest spare time I have tried to find out what would be the right
way to approach this problem.
So I wrote a jmeter test against the Struts ShowCase application, looking for a
good trade-off between ramp-up period, concurrent user and so on.
I have to say that has not been not a piece of cake:
# both opensymphony ognl and patched version of commons ognl give more or less
the same outcomes.
I have also tested against a full application stack, but with no results.
That happens because, IMO, the ognl load is very small compared with I/O
request (servlet, DB access, and so on) which are the really bottleneck.
Any idea, guys?
