Hi there. Many thanks for your replies. They have helped me determine a
direction. It is a great thing to have both options available (and to
better understand the pros and cons of each).
Regards

Quick answers. 2 webapps one core/index each vs. 1 webapp with 2

slightly gentler on your RAM.
I think we should emphasize the *slightly* -- Whatever increase there is
from the solr side is minimal -- none of the memory intensive aspects
are shared across cores. The servlet container may add a little more
memory for each webapp though.
Another thing to consider is that in a multi-core setup, if one core
freezs the JVM (who knows why), it will freeze everything. In a
multi-webapp setup, it would only affect its own webapp.
If you only have a few indexes and the configuration does not change
much, you may just want to stick with multiple webapps. Multi-core is
good for cases where you want to start/stop/add/modify cores at runtime.
