I got iozone from freebsd.cdrom.com and ran it with the following results: Operating System: POSIX 1003.1-1988 IOZONE: auto-test mode MB reclen bytes/sec written bytes/sec read ... 1 4096 4839581 1165084 1 8192 5242880 1123474 2 512 3700856 1245832 2 1024 4660337 1165084 2 2048 5991862 1133595 2 4096 6622585 1113532 2 8192 7401712 1094166 4 512 1123474 798915 ... First of all, aren't reads supposed to be faster than writes? Secondly, are these "normal" results? or can i get better I/O? any input at all will be appreciated. BTW i'm using 8k blocks on the filesystem. thanx viren shah viren@faser.cs.olemiss.edu
