I had been testing DSS lite on 2 different hardware and seems to be getting dismal performance of around 2% of GbE when transfer a single 1Gb file from a T60 with GbE connection on XP-SP2 to the iSCSI volume. When transferring to the NAS share, the network bounce between 2%~14%.

Platform 1
Celeron 2 Ghz with 1Gb RAM on i945 mini-itx with 2x Marvell GbE. NAS and iSCSI Volume in RAID5 - 4disk array (4x 250Gb, Seagate/Maxtor)

Platform 2
Celeron 420 with 1Gb RAM on Supermicro PDSMi-LN4+. NAS and iSCSI Volume in RAID0 - 2 drive array (2 x 250Gb, Seagate).

I'll likely swap the Celeron 420 with a X3210 Quad-core just for comparison. Likely to get the 3ware 9550 later.

At 2% of GbE, the transfer rate is only around 2~3 Mb/sec. That's shockingly slow. Is that the normal performance of Open-E? Or am I missing something here???

I would expect any standard linux distro to be able to handle 20~30 Mb/sec ie 20~30% of GbE bandwidth and a dedicated distro like Open-E to be able to reach 40~50 Mb/sec for RAID0 volumes.
