Thread Subject: matlab becomes very slow if kept open and is unattended for a while

Hello
Well I have observed a couple of times that Matlab becomes
very slow and runs almost like a speed of snail, if kept
open and not attended for a while like a couple of hours.
Say you have started the Matlab environment and then kept
it open and then went on to have your lunch. You will see
that its become terribly slow after you have come back and
the only way is, to close down matlab("which agains take a
lot of time to close") and then restart again
Why so?

I've noticed this. But I think it is just slow to 'wake up' again, but
Matlab won't stay slow after it is completely waked up?

I think it is a side effect of using our beloved Java. Possibly some JVM
threads went to sleep and they need time to all wake up, may be some
scheduling issue. Not sure.
