I'm getting a dissapointingly low performance from the only disk on the ncr0: ncr0: <ncr 53c875 fast20 wide scsi> rev 0x37 int a irq 21 on pci0.13.0 ncr1: <ncr 53c875 fast20 wide scsi> rev 0x37 int b irq 22 on pci0.13.1 [...] da0 at ncr0 bus 0 target 3 lun 0 da0: <SEAGATE ST34371W 0440> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da0: 52MB (8496884 512 byte sectors: 255H 63S/T 528C) This is a dual PII-300MHz system with 64Mb of RAM running FreeBSD 3.2-STABLE from Wed Jul 7. The iozone's numbers are: File size set to 80000 KB Time Resolution = 0.000015 seconds. Processor cache size set to 1024 Kbytes. Processor cache line size set to 32 bytes. File stride size set to 17 * record size. random random KB reclen write rewrite read reread read write 80000 4 3885 1460 4842 4474 415 208 bkwd record stride read rewrite read fwrite frewrite fread freread 988 135635 543 5235 1533 4674 4803 Big things, like Netscape and KDE take very long to start up, probably even longer then they used to take on my older P90 system with the same amount of RAM. What should I be tuning? Thanks! -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
