Re: pf/altq

I've dealt with that much traffic without issue. It all depends on the *type* of traffic though. If you get some really extensive rules going (expensive CPU-wise type rules) you might run into issues depending on the processing power of the machine. Also, your pps could be wildly different than mine, even at the same 100Mbps rate. We ended up moving to a dedicated router for reliability reasons, *not* the incapacity of FreeBSD to handle the traffic with PF/ALTQ.

At 100Mbps, I don't think you will have any issues. Testing against simulated load like your real load is the only way you're going to know for sure, though - so I hesitate to say "It'll work great!"

We were doing transparent filtering (over bridged adapters) with somewhat complex rulesets, for a web-server farm, on 100Mbps, utilizing 80Mbps consistantly. We used altq to prioritize http traffic over everything else.

Cheers,
David

Hello,

We need to replace our bandwidth management solution because it's
not
working properly anymore.
Does anybody have experience with pf/altq in high traffic
production
environments. We expect to run 100Mbps through each pf/altq box.
Man pages don't show shortcomings one may experience in real life.

Any real life experiences you can share will be greatly appreciated.
