[forwarded from isp due to lack of response] Hi, I've just put together a news server. I know it is underpowered somewhat. It is a Pentium 100, 32 MB RAM, wd0 is 540 MB IDE, sd0 is Quantum 730MB, sd1 is Quantum 1 GB. aha0 is 1542cf with 8Mbps scsi bus. sd0 and sd1 are ccd0 (/var/news) with interleave of 65536. News is coming in via a ppp link on a directly attached modem, at about 3-4kbps. It has been running for 36 hours and there is now 475 MB news on /var/news. There is no-one at all reading news. That all sounds reasonable, but I'm not so sure about the stats from top and systat -vmstat. Top shows innd (1.5.1) at 60-70% CPU (39% user, 50% system). Systat shows similar figures. I'm running kernel pppd with compression, and there seem to be about 4000 sio0 interrupts per systat refresh, but it shows 4% CPU for interrupt servicing. /var/news is mounted noatime. innd has 2 MB resident size. Is the CPU utilisation normal for the situation? In a previous incarnation the box was a Linux machine doing the same job under a different admin, and CPU for innd was more like 5-20% with no readers. /* Daniel O'Callaghan */ /* HiLink Internet <http://www.hilink.com.au/>; danny@hilink.com.au */ /* FreeBSD - works hard, plays hard... danny@freebsd.org */
