<p class=MsoNormal>Can someone help me understand the relationship between the
number of Packages in a single RuleBase and PermGen memory consumption? I have a
test that generates 200 rules and then adds those rules as different
packages to a single rule base. PermGen consumption grows near linearly with
the addition of Packages to the rule base and on a default PermGen setting the
JVM runs out of PermGen after about 120 packages.<o:p></o:p></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>It's
not related to Packages, it's related to the number of rules and whether those
rules have compiled java parts - like the consequence, eval etc - each
one adds an additional class.<br>
<br>
<o:p></o:p></span></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Is every new Package and RuleBase backed by a set of
generated Classes? Is there a way to get around the amount of class generation
that is taking place?<o:p></o:p></p>
<p class=MsoNormal>The test has been run against Drools 5.<o:p></o:p></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>You
can use MVEL, which has no class generation. There are improvements we can make
to generated code into a single class and use a switch statement to invoke the
correct part, but we don't have time for that right now, so would need to come
from the community.<br>
