Hello!
We like to propose four new stats. counters to monitor the garbage process
of route cache. This should be useful for tuning and debugging installations
which have a large number of flows.
Tuning is another business but we have played with max_size and gc_thresh
there are more tuning knobs. The number of buckets in the hash table is
something to tune as well be but we have not experimented with this here.
Anyway for most installations the "default" setting does a very good job
but when we see high numbers in the new GC counters one should be warned.
Kernel patch.
