[Cerowrt-devel] ingress rate limiting falling short

[Jonathan Morton]

Remind me: does HTB have a divide in the fast path? ARMv6 and ARMv7-A CPUs
don't have a hardware integer divide, so that can really hurt.

This is fixed I think in ARMv8 and definitely in AArch64, but divides are
still expensive instructions on any CPU.
