iSCSI performance unacceptable

[sebus]

Just for the fun I build another unit with exactly the same spec & this time used FreeNAS FreeNAS-8.0-RELEASE-amd64.Full_Install

Default install with same tweaks as per Gr-R recommendation

Both servers connected to the same switch via identical Cat6 cable

So all in all the hardware is a TWIN, just the OS is different

Then I used Copy Handler 1.32 to copy same 1.59Gb of data from internal HD to both units:

First FreeNAS:

45 sec, avg 36.26 MB/s

Then DSS:

4 min 16 sec, 6.37 MB/s

Surely not what one should/could expect?


And that is exactly what I see during normal use of the machine.
Open-e ISCSI volume can not be accessed when something is writing to it

With FreeNAS I can read (open large rar) while another process writes to the volume (ie file copy)

Can you check the test.log and tell me what the hdparm are for the reads - cut an past on your post.

And where is test.log?
