I set the server-wide setting on most of my servers to 64MB. This
includes my shared hosting servers, where resources are then monitored
otherwise and then clients who may overuse or abuse resources may be
bumped to a more powerful system (VPS, dedicated, or even just a
higher shared plan). So I'd recommend using 64MB, but monitoring
traffic as well --- because that 64MB max limit will be for each
execution of each script. So if you have 100 simultaneous connections
each using the maximum memory allowed by configuration, you're looking
at ~6.4GB memory --- clearly into swap space, and not an optimal
situation.

Ask me about:
Dedicated servers starting @ $59.99/mo., VPS starting @ $19.99/mo.,
and shared hosting starting @ $2.50/mo.
Unmanaged, managed, and fully-managed!
