[Pljava-dev] optimizing java

Hello,
Thomas, I promised making some reports of memory consumption, which seems
strange to me in some cases... I am sorry but I have too much commercial
work now, we are starting a new project and the project with pl/java has
been delayed a little. But I am sure I will do it (hope soon).
I do think that the startup time is really irrelevant if one makes a good
connection pool. Once it starts, the performance is very good.

Regards
Filip
