To get away from the torrent of 1.2 questions, here is one about
jdk1.1.7:
I have a quick question about the jvm's memory usage in linux. For
instance if I have 3 jvm's running (all same version) will there be any
sharing of memory resources between the jvms? As I understand it, the
jdk is built using shared libs so should all of the running jvms be
sharing only 1 copy of these libs in memory ?
Why I ask is that I have tried the above scenario and have found that
having 3 jvm's running uses up almost 3x the memory of having 1 runnning
- leading me to think there is no sharing and wondering how much memory
I'm going to need if I want to have a large number of small
(co-operating) java apps running similtaneously (I know an alternative
would be to use something like echidna which will let multiple apps run
inside 1 vm, but will this is a nice solution it still has a problem
since apps in the same vm are vulnerable to each other, ie. if one of
the apps dies it can take the whole vm and all the other apps in it with
it).
TIA,
Maksim.
