Apache - High Memory Usage

Kind of an odd problem but I'm moving my stuff to a new server and for some reason Apache is using a lot more memory on the new server than on the old server.

I'm hosting the same web sites and (I think) I have all the same software installed. Both running Fedora Core 4. The new server is running the 64 bit Linux. The new server is a dual core athlon - the old has 2 Xeon CPUs. Both have 4 gigs of ram.

On the new server running top it shows:

virt 201m
res 53m
shr 11m

On the old server:

virt: 50k
res 14m
shr 10k

So - what am I missing? Why is the new server using so much more ram?
