Re: [jetty-users] jsp-impl Apache vs. Glassfish - BIG memory difference
Otis,

I haven't heard of anything particular regarding increased memory usage with apache jsp.  The way you have configured the glassfish impl it will use the eclipse ecj compiler, which is exactly what the apache impl does.

Do you have any heap dumps to show what the main memory hog is?

BTW I would always recommend for a production system to precompile jsps ...

cheers,
Jan

Hi,

After switching from Jetty 8 to Jetty 9 we saw an increase in memory usage.  We have not been able to find the source of this issue :(

In the process we we changed from

--module=jstl jsp-impl=apache


to:

--module=jstl jsp-impl=glassfish -Dorg.apache.jasper.compiler.disablejsr199=true

And the memory dropped significantly!

RAM:


Is this a known thing?

Thanks,
Otis
