This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigEF0342819F6957260431579E Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable As some of you know back at BSDcan 2007, I made it known that we had seen BIND9 performance suffer under FreeBSD and that under threaded build on SMP systems, Linux had blown FreeBSD out of the water in terms of performance. As it's now (well was) EuroBSDcon, one of our engineers re-ran the query test I mentioned back at BSDcan and it looks like the work kris@ has spearheaded has paid dividends. Re: -=3D- Last night I built a disk with the August snapshot and re-ran the test. FreeBSD performance is indeed much improved -- almost as good as Linux. fbsd-7-current (200704) 44K queries/sec fbsd-7-current (200708) 84K queries/sec Gentoo Linux (2.6.20.7) 93K queries/sec Fedora Linux (2.6.20.7) 87K queries/sec Disk-to-disk copy speed is 90 MB/s for Linux and 20 MB/s for the April snapshot of FreeBSD; it is unchanged for the August FreeBSD snapshot. This is reassuring because the zone files should be in memory and disk performance shouldn't be an issue. In any case, FreeBSD-current has greatly improved between April and August. -=3D- (FYI - the disk controller on these boxes are mpt Serial SCSI) Not quite there, but a significant improvement nonetheless. If anyone needs more information about the test, let me know.
