[jira] [Updated] (CASSANDRA-13078) Increase unittest test.runners
to speed up the test
[ https://issues.apache.org/jira/browse/CASSANDRA-13078?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jay Zhuang updated CASSANDRA-13078:
-----------------------------------
Description: The unittest takes very long time to run (about 40 minutes on a macbook). By overriding the [{{test.runners}}|https://github.com/apache/cassandra/blob/cassandra-3.0/build.xml#L62], it could speed up the test, especially on powerful servers. Currently, it's set to 1 by default. I would like to propose to set the {{test.runners}} by the [number of CPUs dynamically|http://www.iliachemodanov.ru/en/blog-en/15-tools/ant/48-get-number-of-processors-in-ant-en]. For example, {{runners = num_cores / 4}}. What do you guys think? (was: The unittest takes very long time to run (about 50 minutes on a macbook).
