<P><FONT SIZE=2>Its not just about throughout though, there's reducing thread contention (rsa auth calls take 3 seconds where vm locks up and I want other users to be less affected by this, so we spread them around X images) as well as fault tolerance (one vm goes down, others are there to let you log in again, and some users aren't affected at all). Are you against data sharing? Isn't that what GemStone is for? ;)<BR>

Hi Philippe,<BR>
<BR>
Are you answering on behalf of Udo, or are you just providing a general list<BR>
of reasons why someone might want to run multiple instances? Are you making a<BR>
distinction between "scaling" and "computer with more than one CPU/core" or<BR>
are the two reasons equivalent? How many pages per second are your serving<BR>
such that one instance is inadequate?<BR>
<BR>
