[jira] [Created] (TS-931) cluster latency too high, about 24ms

cluster latency too high, about 24ms
------------------------------------

                 Key: TS-931
                 URL: https://issues.apache.org/jira/browse/TS-931
             Project: Traffic Server
          Issue Type: Improvement
          Components: Clustering
    Affects Versions: 3.0.1, 3.1.1
         Environment: cluster type 1, content hashing
            Reporter: Zhao Yongming
             Fix For: 3.1.1


when we enable full clustering, the performance is unacceptable, it add about 24ms per request. we'd expect <10ms latency  for each cluster request.

this issue is for weijin :D

---------------------------

Base on the current framework, it`s hard to reduce the cluster rt to smaller than 10ms. I will continue to focus on performance issues。

[jira] [Updated] (TS-931) cluster latency too high, about 24ms

Posted by "weijin (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/TS-931?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

weijin updated TS-931:
----------------------

    Attachment: cluster_performance.patch

This patch will reduce the cluster response time. In my test, cluster memory cache hit:
300qps(9.9ms~10.2ms); 600qps(10.5ms~12ms). I did not test the rt under very high pressure.
