Subj : Performance?

Hi!

I'm using Rhino as a way to accomplish dynamic extensions (aka portlets) 
in our CMS, and also as a shell-type tool to access the system.

Functionality wise everything is the way I want it to be, but the 
performance is a bit troubling. Most of the time we do 5-10 lines of 
code to get some data by calling services, then transforming it to be 
suitable for HTML output. What surprised me is that these small snippets 
can take about 100ms (and sometimes up to 500ms) to execute.

I've tried all the usual suspects: doing a shared scope, calling 
setOptimizationLevel(9) (which made no difference at all), etc.

My question is:
Are there any known performance problems in Rhino? Are there any 
regressions in the latest version? (i.e. would trying an earlier version 
be a good idea?) And, are there any planned fixes for performance in the 
somewhat near future?

I realize that for client-applications performance is maybe not so 
important, but when you use it the way we do it's very important. So, 
any ideas are welcome.

regards,
   Rickard
