Any idea when you will been able to help ?

Are you able to help ?

I use ATTO.
I have attached 2 screenshots.

yes.

Then I get wirespeed. I get 100 MB/sec write and 100 MB/sec read.

Great ideas. But without luck.

I have previosly tried different SAN hardware, different ESX hardware, different NIC and different switches...

Same performance when using a ramdisk.
I am not using Jumboframes and I am using a single path.

I know.
Locally on the SAN I have 300 MB/sec Read and 250 MB/sec write performance.

On the Virtuel machine I have 110 MB/sec write and 30 MB/sec read.
The read performance is OK when the transfer size is below 64 KB

Disabling the ACK make the read performance a little bit worse.

Hi. I am trying version 6 of the iSCSI SAN free edition.

But when I am testing the performance I get poor read performance.
Write performance is wire speed.

I have been reading the forum but without luck and in a dead end.
Please help.
