Max_IO is set to double from what it was before, Hyper-V allows it and We have had appliance builder requests to see if it was a problem to increase The number. Ringbuffer size for storvsc is now increased because I have seen A few buffer problems on extremely busy systems. They where Set pretty low before. And since max_io_requests is increased I Really needed to increase the buffer as well. >> And will allow more IO requests to take place for the SCSI driver. > >Which means what, better throughput?
