Hi all.
Just finished installing FreeBSD-2.0 on my new machine, and wanted to get
some feedback from others with similar hardware as to whether or not my
machine is a) configured right and b) getting the best performance possible.
Machine is:
dx4/100 VLB Motherboard
486dx2/66 CPU
16MB RAM (single 72pin SIMM)
Buslogic 445S VLB Controller (terminated) (id7)
Micropolis 1GB SCSI-2 hard disk (unterminated) (id0)
Panasonic SCSI-2 CDROM (terminated) (id1)
dmesg reports:
bt0: Bt445S/ 0-PCI/EISA/VLB(32bit) bus
bt0: reading board settings, busmastering, int=11
bt0: version 3.37, async, parity, 32 mbxs, 32 ccbs
bt0: Enabling Round robin scheme
bt0 targ 0 lun 0: type 0(direct) fixed SCSI2
bt0 targ 0 lun 0: <MICROP 4110-09TBCU0322LHT01>
bt0 targ 1 lun 0: type 5(readonly) removable SCSI2
bt0 targ 1 lun 0: <MATSHITACD-ROM CR-503 1.0f>
With a 40MB iozone test (iozone 40):
Writing the 40 Megabyte file, 'iozone.tmp'...25.062500 seconds
Reading the file...16.335938 seconds
IOZONE performance measurements:
1673537 bytes/second for writing the file
2567531 bytes/second for reading the file
On the micropolis I've jumpered "Sync Negotiation Master" and "Sync
Termination Master" and on the bt445S I have it switched for slave
mode. If I put evreything to its default, I get 1MB/second slower
on reads, but writes are the same.
I'm a tad confused, and perhaps asking a lot to get faster than this,
but I would have expected a bigger increase in performance between
ISA aha1542 and VLB bt445s ...
Cheers
Leigh
