[opencms-dev] memory usage of JVM when runnung OpenCMS

[Michael Hoennig]

Hallo Nick,

Thank you very much.  It is about what I expected.  The site which I have
in mind does not fit into any memory of Intel 32 Bit CPUs anyways.  Thus,
I guess the 4 GB requirement for large OpenCMS sites comes more from the
database than from the JVM.
