Thanks! Legend! :-D It seems to be mostly an excerpt from one (or more) of the official training program curriculum. Here's an interesting question for everyone: Even though we all know, in theory, how to make a firewall table most efficient (e.g. match tcp-new packets, mark the stream, and then process against the marks) hands up who has a 'perfect firewall rule table' on a production system that has been in service for more than 2 years? ;-) NOT ME! :-} Cheers, Mike.

The slides actually condense down a lot of the major points and yes there's slides dedicated to the discussion on BGP (more info below) Couple of important ones I got from it:
*Reducing Average number of rules that packet * *need to pass before it is captured can * *significantly improve your firewall performance* *● Make use of action=jump*
*● New Mangle Actions “snif-tzsp”,”snif-pc” to send * *packet stream to remote sniffer. *
*Layer-7 should be used only on traffic that can't be identified any different way● Layer-7 should be used only as trigger - use connection-mark or address- list to keep track of related packets or connections● Do not use direct action (like accept, drop) in Layer-7 ruleAll dynamic routing protocols in RouterOS v6.x are limited to a single core.- One BGP full feed will take 1-3min to load on CCR - Two BGP full feeds will take 6min to load on CCRAll routing protocols will be updated to multi-core for RouterOS v7*

Hi Andrew,
Thanks for the headsup - does it include some discussion about updating large BGP tables? I understand that BGP updates use a single CPU core, and if there are lots of updates, it pegs that core at 100% pretty much constantly! ;-)
I'll try to find a few moments to take a look at the recording - in the meantime, any chance of an executive summary? :-}
(i.e. what are the one or two major points to your interest?)
Cheers!

This presentation by Janis has a lot of detailed info about the current status of routing functions in v6 and the best way to fully utilise the performance of them; also what will be changed in v7!
