Multiply that number (10k servlet requests per day) by 100 (one hundred),
and then you'll end up with a rough number of _servlet_ requests we're
serving each single day... Multiply again by 10 and that's what we're going
to end up by the end of the year...

And of course, all static content doesn't even try to get into the VM...

Good... Prove it to me. Come up with a proposal of some friggin' sort...
FWIW even 4.2.x doesn't address any of my concerns, and it's not even out
working yet... Talking about 5.0 is a little bit "premature" maybe?

But that's my vision... The vision of an old fart who has been around for
quite long and is more concerned with numbers than whether we support JMX or
not...
