Re: Idle-max value in Dynamips

It does help considerably with CPU utilization. I have noticed a small
problem that idlemax 100 presents. Stuff like interfaces coming up,
frame-relay lmi communications, and general router responsiveness is much
slower. I haven't add a chance to play with different values, but I might
try something a little more liberal with resources. Maybe a 750 or 500.

It's a good trick, but it still is no substitute for proper idle-pc
tweaking.
