If you're using CF 4.5.1, though, you will see the high memory usage
mentioned by Jake. 4.5 handles memory differently than previous versions.
For memory management, CF uses a third-party product called SmartHeap. In
4.5.x, SmartHeap doesn't release any memory back to the operating system as
it did in earlier versions.
This isn't necessarily a bad thing. The reason 4.5.x does this is to
eliminate the performance cost of releasing and reacquiring memory,
following the assumption that it will probably need the memory in the
future. CF isn't designed to share a server with other applications. As long
as you don't have any memory leaks in external components, including
database drivers, you shouldn't have any problems. If you do have memory
leaks, though, you'll end up cycling your server more than you'd like if you
run 4.5.x.
