My last message didn’t show up properly due to some formatting errors.
So, I am sending it again
I am using nbd over high latency network (100 ms ).
Currently maximum size of nbd io operation(amount of data fetched in one
request)
I can achieve is 130kb and it gives very poor disk performance.
I tried recompiling nbd driver code so as to increase max_sector_kbproperty of
disk queue.
I added following two lines to nbd_init function
blk_queue_max_hw_sectors(disk->queue, 65536);
disk->queue->limits.max_sectors = 4096;
But these modifications changed nothing.
Do you have any idea what can I do to increase size of nbd io operations?
I would like it to go as high as 4MB.
