On a busy, CPU-based router (eg. 7206VXR as a DSL LNS), a moderate
"scheduler allocate" (eg. scheduler allocate 3600 400) may help as a
If your router is *really* under load (and has a lot of free RAM), it
might also help to nail down the buffer counts so it doesn't have to
worry about memory allocation.
buffers small permanent 3072
buffers small max-free 3072
buffers middle permanent 4096
buffers middle max-free 4096
buffers big permanent 512
buffers big max-free 512
buffers verybig permanent 128
buffers verybig max-free 128
buffers large permanent 16
buffers large max-free 16
buffers huge permanent 16
buffers huge max-free 16
(these are very specific to the features you use - "show buffers"
tells you if you're exceeding the buffers you've allocated)
