Re: OID compression/suppression support


I strongly object to what I've seen being proposed that is "pure"
OID compressing (and any compression or other operation that is
CPU intensive).

Elimination of redundant information is very important and is
a HUGE win, but only when it is NOT at the cost of CPU cycles.

If anyone doesn't understand the reason why CPU usage is VERY
important, send me your phone number and best time to call and
we can have a chat.
