hi, everyone!
I test RGW get obj ops, when I use 100 threads get one and the same object ,
I find that performance is very good, meadResponseTime is 0.1s.
But when I use 150 threads get one and the same object, performace is very
bad, meadResponseTime is 1s.
and I observe the osd log and rgw log,
rgw log:
2014-07-15 10:36:42.999719 7f45596fb700 1 -- 10.0.1.61:0/1022376 -->
10.0.0.21:6835/24201 -- osd_op(client.6167.0:22721 default.5632.8_ws1411.jpg
[getxattrs,stat,read 0~524288] 4.5210f70b ack+read e657)
2014-07-15 10:36:44.064720 7f467efdd700 1 -- 10.0.1.61:0/1022376 <== osd.7
10.0.0.21:6835/24201 22210 ==== osd_op_reply(22721
osd log:
10:36:43.001895 7f6cdb24c700 1 -- 10.0.0.21:6835/24201 <== client.6167
10.0.1.61:0/1022376 22436 ==== osd_op(client.6167.0:22721
default.5632.8_ws1411.jpg
2014-07-15 10:36:43.031762 7f6cbf01f700 1 -- 10.0.0.21:6835/24201 -->
10.0.1.61:0/1022376 -- osd_op_reply(22721 default.5632.8_ws1411.jpg
so I think the problem is not happened in the osd, why osd send op replay in
10:36:43.031762 , but rgw receive in 10:36:44.064720 ?
