I have a couple of quick questions: 1) The system has 2MB of L2 cache. Would bumping that to 8MB make a noticeable difference on, say, a make buildworld? 2) I've installed a Tekram DC-390f U/W SCSI card, and two U/W drives: a 4GB IBM and a 9GB IBM. Throughput is dismal, to say the least: bonnie++ on the 4GB: Version 1.93c ------Sequential Output------ --Sequential Input- --Ran= dom- Concurrency 1 -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --See= ks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec= %CP gopher.honeypo 300M 6 99 7420 69 3631 41 12 99 7568 42 168.2= 65 Latency 2663ms 120ms 676ms 1859ms 25477us 3951= ms Version 1.93c ------Sequential Create------ --------Random Create----= ---- gopher.honeypot.net -Create-- --Read--- -Delete-- -Create-- --Read--- -Dele= te-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec= %CP 16 967 96 2611 94 1438 89 975 96 2496 95 1661= 91 Latency 369ms 300ms 353ms 361ms 225ms 240= ms bonnie++ on the 9GB: Version 1.93c ------Sequential Output------ --Sequential Input- --Ran= dom- Concurrency 1 -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --See= ks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec= %CP gopher.honeypo 300M 6 99 9349 94 4957 68 11 99 12079 96 235.7= 106 Latency 1586ms 145ms 138ms 803ms 13585us 1979= ms Version 1.93c ------Sequential Create------ --------Random Create----= ---- gopher.honeypot.net -Create-- --Read--- -Delete-- -Create-- --Read--- -Dele= te-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec= %CP 16 92 11 4292 99 155 12 83 10 4124 99 257= 24 Latency 488ms 1891us 262ms 364ms 2565us 257= ms Is there some "DONT_MAKE_SMALL_WRITES_CRAWL" setting that I've missed somewhere? Running nightly backups on the machine takes forever. I really don't expect miracles from the little fellow, but still...
