AOLserver 3.x can be configured to gather command stats which you can view
with the "ns_stats" command. This works by registering a command trace which
counts commands per-thread and flushes them to a shared table occassionally.
Of course all this is undocumented but its use can be figured out by looking
at the nsd/tclstats.c code. It does affect performance in two ways - first,
the monitoring and occasional lock around the shared table and second tracing
disables the byte code compiler in tcl 8.x for special internal commands
(e.g., if, foreach).
I removed this from 4.x because it was being used much and requred an
undocumented, non-virtual server safe API no longer available.
