I like the code snippets and the numbers that you are posting.

Using getnext instead of get is IMHO the right decision. In 3.0.0,
there is an asynchronous walk command. Using this asynchronous walk
has some benefits over a pure Tcl solution which calls getnexts. The
most important is that the walk command uses getbulks internally. So
if you are talking to SNMPv2c or SNMPv3 agents, you will see a real
speedup without any extra Tcl code.

The 3.0.0 walk implementation may need some enhancements so that you
have better control where it stops and that you can have non-repeaters.
