Please recommend a better set of parameters about JVM parameters optimization

Hi, @rubendel ,Could you recommend a better set of parameters about JVM parameters optimization. Now We found that memory has been increased to 100% and caused service almost no respons.

Please state your version etcetera and what you are doing on this BIMserver. When memory is at 100%, most of the CPU time will be spent on garbage collection. So you might want to try and increase the amount of heap memory.

hi, @rubendel
I find this issue exist in version from 1.5.64 to 1.5.68-SNAPSHOT when I do stress testing by checkinFromUrl interface to address ifc（deserializer is Ifc2x3Stream）, serial operation，
I found that about 7000 IfcGeomServer were not exited resulting in 64G memory consumption

What platform are you on?

[hujb2000]

Linux and CommonsPoolingRenderEnginePoolFactory

Sorry, do you mean to say you changed the code to use another pooling engine?
