[rules-users] Drools 5.2 performance building KnowledgeBase

[darktyco]

I forgot to answer your other question: I'm on Drools 5.2. I had tried the
Drools 5.3 Beta 1 distribution but there was no improvement- it seems
something was fixed specifically in MVEL 2.1 Beta6.

Also, to Thomas: I have to specify -Xmx512m in order to run a pretty bare
minimum unit test (this does include a Spring application context but it is
very small) using this Drools setup to run or I will get an OOM Java Heap
exception within seconds. It is actually kind of strange how quickly the
exception is thrown. I will double check the 512 figure and get back to you
if I can indeed get it to run with less memory, I really dislike spreading
bad info around. The full Webapp needs more than that plus a MaxPermSize
increase, but there is a lot of other stuff going on in the war.
