Dell SAS 5/i poor performance

This story begins about 3 months ago, when we have received first server from new Dell’s server line (PowerEdge 1950/2950). That server was a Dell PowerEdge 1950 with one Dual Core Xeon 5110 and two SATA drives connected to integrated controller. That server (in my mind) may be a good replacement for old PowerEdge 850 servers line. In a few weeks after first server delivered to our customer we have noticed about poor IO performance. I have made a few tests with bonnie++, and tests results was very terrible. There was about 30% difference in IO peformance between Dell 850, Dell 1950. Even my home PC with IDE drive was faster.First i have changed OS from FreeBSD 6.2 to Debian testing/unstable - results was same. Googling was a second step but there is not a lot of info about Dell 1950 performance. I have found only 2 posts on boards, but that posts was without replys. With all that info (bonnie test results and two posts on boards) i have write e-mail to Dell. In their reply they asked my to perform some tests with IOMeter using attached profile. Here is some info about test systems:
