Reducing the number of indexes (particularly text indexes), reducing the
amount of work done by the indexed methods/attributes, reducing the
number of metadata fields (and the work done by the methods/attributes
that are associated with each).

I might try the CallProfiler product against each of the methods that
are called by the indexes.  If one of them (or any of them) take a long
time, try to prevent that from happening.

Unfortunately, no.  Memory leaks are tricky and even with LeakFinder can
take inordinate amounts of time to debug.

You may want to use my AutoLance product to prevent you from going
insane while you try to hunt the leak down.  It only works on Linux, but
it is capable of restarting Zope if memory usage hits a certain
threshhold, which prevents the box from ever getting into a state of
churning through virtual memory use when memory exceeds physical RAM.
