<DIV dir=ltr align=left><FONT face=Arial><SPAN

assert objects into working memory, pattern matching is done at the time of
assertion only, while this process, if we create more variables in "<FONT

creating more overhead(memory perspective) while pattern matching. When we
assert thousands of objects(events) into working memory, i think Drools engine
creates several objects internally(in rete network which i am not aware), i
think that would be the overhead.</SPAN></FONT></DIV>

<DIV></DIV>The answer is:<BR><BR>42. <BR><BR>Or, perhaps, the length of a piece
of string. <BR><BR>It really varies with how much memory you want to throw at
it, thats all really. The effectiveness of the RETE network may also add some
overhead. <BR><BR>I have heard of people pushing in millions of facts into one
working memory, but that would tend to be extreme - and it will use a lot of
memory. <BR><BR>IN 3.2 there are some added efficiencies over 3.0, when it comes
out. <BR><BR>
