Hi Robert,
We're using 64bit tomcat. Three instances clustered in much the same way
Simone specified.
Strictly speaking they can be 32bit tomcats - none of them is using more
than a couple of GB of RAM (even though I've set it to 5GB each instance).
This would also give the JAI native benefit.
That said, this setup is more than fast enough and can easily handle the
load - even of the "big launch" where an order of magnitude more people
used it than are ever going to in big usage.
So any setup should work probably. :-)
We're probably a similar size organisation to yourself.
