LSI would leave no stone unturned to make the performance better for megaraid controllers under Linux. If you have some hard data in relation to comparison of performance for adapters from other vendors, please share with us. We would definitely strive to better it.
The megaraid driver is open source, do you see anything that driver can do to improve performance. We would greatly appreciate any feedback in this regard and definitely incorporate in the driver. The FW under Linux and windows is same, so I do not see how the megaraid stack should perform differently under Linux and windows?
It is not the driver per se, but the way the memory which is the I/O source/target is presented to the driver. In linux there is a good chance it will have to use more scatter gather elements to represent the same amount of data.
