Hi Folks ,
I'm in progress of swift QA.
Also interesting about the number of PUT/GET operation in your swift-bench
configuration.
Well , I thought that swift should handle as much as I set in bench.conf.
However , the performance degradation came after 40000+
Does my configuration reasonable in your mind ?
[bench]
auth = http://%swift_ip%:8082/auth/v1.0
user = admin:admin
key = admin
concurrency = 100
object_size = 4
num_objects = 100000
num_gets = 100000
delete = yes
The performance degradation of swift
PUT result from 1200/s to 400/s
GET result from 1800/s to 800/s (but failures around 400)
DELETE result from 800/s to 300/s (lots of failures)
1. Does my configuration is reasonable in reality ?
2. I saw that most of failures is been log as "object-server failled to
connect to %storage_ip%:%port&/%device% ... connection timeout(0.5)"
What's the reason cause the kind of timeout? Also the loading is very
low at this period and almost 0 request send to storage-nodes.
3. Another odd behavior , swift proxy does not consistent send requests to
storage-nodes . In my 100000 PUT period. The storage-node's loading is
not balanced
.
It might in 70% loading and 10% in next second. Seems is a
periodically behavior.
I'm really confusing about this issue.
