Hi I tested that on Linux an FreeBSD 10, and for full BGP table (680k routes) the scan took about 1.3 s on Linux and about 2.4 s on FreeBSD 10. Unfortunately i don't have FreeBSD 11 here now to test it. Also it is 'system freeze' or just BIRD freeze? There are two possible issues - logging and memory: Enabling 'debug {routes}' or 'debug all' for Kernel protocol could slow down the scan significantly. Kernel table scan on BSD require a buffer for all routes, so it may require some nontrivial additional memory during routing table scans. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
