One of the people in the list ask about tuning option to the SRP driver 
 
 
"...Now in regards to performance - In the linux environment, on the
host/initiator there were numerous parameters that could be toyed with
to
boost performance.  Specifically, there is a parameter called
max_xfer_sectors_per_io in a file called modprobe-openib.conf.  By
changing
the value of this parameter, performance via srp to srpt and finally to
disks could go up and down dramatically..."
 
Do you have nay idea of similar parameter in windows SRP driver ?
I found  p_config->MaximumTransferLength       =
SCSI_MAXIMUM_TRANSFER_SIZE; 
which is 1K*1K.
 
Does this value can be change ? Do you think it will affect the
performance ?
