PermGen seems like an odd item to share... though I
guess all those java.lang.Package, java.lang.Class,
java.lang.Method, etc. objects can really beat a
system down.
The sharing is not for capacity purposes, merely to reduce JVM startup time.
I was under the impression that only java.* classes were
shared, and not just anything that was loaded by a bootstrap
classloader
That is likely correct. Since we use the -server version pretty much
exclusively, it's a don't care for us.
Since apparently this conversation clears some matters up, even for
gurus, would one of you care to back-up a couple of messages, and
re-state the final consensus in English for us mere mortals ?
Like what gets shared when, in a usual JVM 1.5+ /Tomcat 5.5+ context,
with say two parallel instances of Tomcat running on the same host ?
(and what is PermGen ?)
Thanks.
