I am using nbd over high latency network (100 ms ). Currently maximum size of
nbd io operation(amount of data fetched in on e 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_kb” property 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;
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.
