[Gluster-users] Slow on writing

[Alexey Shalin]

I do not think that isssue with network
I have just tested mount -t nfs gluster:/volume /mnt

and read speed very high on small files:

for example:

Write
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.0357166 s, 573 kB/s

read
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 3.15e-05 s, 650 MB/s

Write
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.0455507 s, 450 kB/s

read
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 3.143e-05 s, 652 MB/s

Write
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.0196823 s, 1.0 MB/s

read
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 2.5493e-05 s, 803 MB/s

write    speed    very   slow   under   nfs   mount       (
nfs   mount -o rw,rsize=65536,wsize=65536,proto=tcp,soft,intr,noatime,noauto,async,nodiratime 192.168.15.165:/storage /storage)


so i renounted /mnt with
nas.storage:/storage /storage glusterfs defaults,_netdev 0 0

and got
Write
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.00244953 s, 8.4 MB/s
read
10+0 records in
10+0 records out
20480 bytes (20 kB) copied, 0.00195908 s, 10.5 MB/s


as u can see:
write speed higher then nfs
but read is lower then nfs
