Hi all, I want to know is there a way to speed up gnbd-server? I have a "big" (~8TB) free web store based on (g)nbd. (4 server + 1 client) When I try to read linear the one big device, it can generate 380-400 Mb/s transfers on Gig-Eth. But when I start the web serving from it, the result is only 80-90Mb/s , and the client's load goes up to 100-150! This is the best performance what I can set up and the settings are these: Scheduler: deadline nr_requests: 255 read_ahead_kb: 0 iosched: front_merges: 0 read_expire: 50 The all server's load is always ~1.00 (0.95-1.14). Is there a way to stress more the servers? (And with small modification the code?) GNBD 1.0.0 no cluster, fs: xfs I try the nbd, enbd, anbd, and gnbd, but the gnbd's stability is the best! ;-) The another nbds always generate a deadlock for me...
