Mark Robert Miller commented on HBASE-23806: -------------------------------------------- I look at this as not likely something that will be contributed back, but that will demonstrate the upper bounds of how fast tests can run. Once you are running efficiently in parallel on a lot of cores, it takes a little extra to keep all those cores busy vs having a long tail of less and less cores being utilized. This can have a very large difference, and while you can't always get there with standard test systems, it's good to know how far off you are as well. The order you start the parallel tests in and how you distribute them across jvms on good hardware can easily half the test time or more. > Provide a much faster and efficient alternate option to maven and surefire > for running tests. > --------------------------------------------------------------------------------------------- > > Key: HBASE-23806 > URL: https://issues.apache.org/jira/browse/HBASE-23806 > Project: HBase > Issue Type: Wish > Reporter: Mark Robert Miller > Priority: Minor > > With HBASE-23795, the hope is to drive tests with maven and surefire much > closer to their potential. > That will still leave a lot of room for improvement. > For those that have some nice hardware and a need for speed, we can blow > right past maven+surefire. -- This message was sent by Atlassian Jira (v8.3.4#803005)
