Following the extended discussion of system benchmarks here are some
actual numbers from a FreeBSD box - if anybody has the time to run
similar numbers on linux boxes I will happily collate the data. John 2.93 GHz Celeron D, 768 MB ram FreeBSD 6.2 bonnie++ -f 0 -d . -s 3072 -n 10:100000:10:10 Key: IDE = 80 GB IDE, soft upodates, atime on IDE-R1-atime = 300gb raid 1 (mirror) IDE, atime on, soft updates IDE-R1 = 300gb raid 1 (mirror) IDE, no atime, soft updates IDE-R1-sync = 300gb raid 1 (mirror) IDE, no atime, sync IDE-R1-async = 300gb raid 1 (mirror) IDE, no atime, async SATA-R10 = 1.5TB raid 10 sata on 3ware 9500S-12. no atime, soft updates v4 = raiserfs v4 from namesys on a 2.4ghz xeon ext3 = ext3 from namesys on 2.4ghz xeon Version 1.93c ------Sequential Output------ --Sequential Input- --Random- Concurrency 1 -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP IDE 3G 40181 22 12106 6 36944 12 99.4 7 IDE-R1 3G 34511 20 14857 8 54482 19 121.7 9 IDE-R1-atime 3G 34426 21 14832 8 54402 18 122.1 9 IDE-R1-sync 3G 4904 8 4248 4 53750 18 103.7 8 IDE-R1-async 3G 34405 20 14877 8 53579 18 122.6 9 SATA-R10 3G 85375 53 25188 14 49751 17 454.1 33 v4 3G 37579 19 15657 11 41531 11 105.8 0 ext3 3G 35221 22 10987 4 41105 6 90.9 0 Version 1.93c ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files:max:min /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP IDE 236 8 5071 73 9954 35 229 7 4354 68 +++++ +++ IDE-R1 460 19 5524 76 13606 86 301 10 4576 65 +++++ +++ IDE-R1-atime 377 15 4368 63 11580 70 395 13 5061 78 11642 90 IDE-R1-sync 107 12 6027 86 +++++ +++ 112 12 5466 83 19644 82 IDE-R1-async 370 15 4609 66 18905 49 376 12 5583 84 11427 90 SATA-R10 973 41 7365 98 13281 84 1079 38 5877 79 12875 85 v4 570 39 746 17 1435 23 513 40 104 2 951 15 ext3 221 8 364 4 853 4 204 7 99 1 306 2 Notes: The 3ware card is somewhat bus limited because it's in a 32bit PCI slot in a 64 bit slot I'd expect better sequential read performance. This also drives up the CPU number due to bus contention. The read numbers for ext3 and raiserfs look suspect Stripe size for the 3ware raid 10 is 256k all file sytems were live and had other files on them - virgin file systems may perform very differently.. Conclusion: ufs2 is pretty similar to ext2 if not a little better but not as fast as raiser4. sync is a big drag but async makes almost no difference over soft updates. atime/noatime doesn't make a whole lot of difference on this test. ~ |
