[ovs-dev] [PATCH ovn repost 0/7] Reduce memory consumption and time for Load_Balancer benchmark

[Ben Pfaff]

Apologies for repost; I forgot to tag this as "ovn" in the first
posting.

For the benchmark at
https://mail.openvswitch.org/pipermail/ovs-dev/2021-July/385333.html,
this reduces memory consumption from 115 GB to 17 GB and elapsed time
from 19 minutes to 5 minutes.

I think there's headroom for more improvement, because Leonid has some
cleverness that I haven't been able to successfully work in yet.

  Intern all the matches and actions.
