I was running FreeBSD 5.0 on an 8G drive. I recently upgraded to a Western Digital ATA100 40GB drive and loaded FreeBSD 5.1. I expected to get improved drive performance, however, my motherboard would only do UDMA-33. So, I picked up a Maxtor SATA/150 PCI Combo card. It's supposed to do ATA-100. My dmesg indicates that it is running UDMA-100, but my disk dump performance is still pathetic. Here's a dd sample: tigger# dd if=/dev/ad8s1d of=/home/chris/tmp.dat count=10000 10000+0 records in 10000+0 records out 5120000 bytes transferred in 2.292473 secs (2233396 bytes/sec) ~ 2MB per second?? It was about 1.8MB per second before I upgraded. The only thing I can attribute the marginal speed-up to is the faster drive rotation speed (7400 RPM). Attached is my dmesg dump. The ad8...UDMA 100 statement is near the bottom. Can anyone provide any insight? Thanks in advance. Chris tigger# dmesg | more Copyright (c) 1992-2003 The FreeBSD Project.
