Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi All:) I'm testing a honking reverse resolver system for use in resolving web logs. It's an Abit KT7 system with 1.1 GHz processor and 768 MB of ECC ram running 4.1-stable as of about a month ago. I'm looking up the IP addresses with up to 1500 or so processes each taking a list of addresses and running gethostbyaddr() on them. I've increased net.inet.udp.recvspace to 192k. Is there anything else I can do to tune the system? I'm particularly perplexed that a K6-200 system I had was cpu bound running named and achieved ~200 resolves/sec; my spiffy new 1100 MHz K7 is struggling to double it. Any suggestions welcome! --- David To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
