Server got about 8GB ram, x8dth board etc., Raid5ee with 4 HDD’s etc.

After I created the targets and successfully connected to the server and on these targets, I tried to do some tests with IO-Meter. (100% sequential, 10MB files, 100% read or write)

I think the performance is not the best?:

In read mode I got about ~240 Mb/s
In write mode the first second I got about 380 Mb/s, but after the first second the speed goes down very fast to 50-80 Mb/s and below.

Any idea why the write speed is just lower than iscsi?
Maybe a configuration problem of my Qlogic card in the server?
I have excatly the same problem.
My configuration
Supermicro X8sax mainboard
intel xeon 5504 processor
2 gb ram
supermicro 24 bay chasi with 16 seagate 1 tb sas disks(7200 rpm) Raid5
qlogic 2562 8gb fibre card
connected to macpro with atto 82en 8 gb fibre card.
Write starts 350 mb/s after seconds goes down 30 mb/s.
Reading about 400 mb/s.
