             Summary: Slow Ignite Cache with multi-nodes
                 Key: IGNITE-8117
                 URL: https://issues.apache.org/jira/browse/IGNITE-8117
             Project: Ignite
          Issue Type: Improvement
          Components: cache
         Environment: OS: Ubuntn 14.04.3 LTS


Ignite: 2.4



            Reporter: Rick Lin
             Fix For: 2.4
         Attachments: WriteKV.java

Dear sir,

I am running Ignite in my project about  with three nodes:

{color:#14892c}Three nodes: "ubuntu7","ubuntu8","ubuntu9"{color}

{color:#14892c}cacheConf.setIndexedTypes(String.class, String.class){color}



When using above setting for
 * Put,
 * putAll,
 * SqlFieldsQuery,
 * IgniteJdbcThinDriver,
 * IgniteDataStreamer add
 * IgniteDataStreamer addAll

, there are a situation about data latency, and the experiment results are in the following.

One node(ubuntu7)


Two nodes(ubuntu7 write and ubuntu8)


Three nodes(ubuntu7 write, ubuntu8, and ubuntu9)

>From above results, these tables show that the three ways: put, SqlFieldsQuery, IgniteJdbcThinDriver
have gradually bad performance on data latency  with increasing ignite server nodes, and
the other ways: putAll, IgniteDataStreameradd, and IgniteDataStreameraddAll have better performances.

I don't know if the testing via my java codes are suitable and correct to show these results
or not.

Here, i provide my codes to reproduce my experimental situation.

{color:#14892c}*Attached is my codes for your reference.*{color}

if any further information is needed, I am glad to be informed and will provide to you as
soon as possible.

If you have any idea about this issue, I am looking forward to hearing from you.

Yours sincerely,
