> [Python] Reduce runtime of builds in Travis CI
> ----------------------------------------------
>
> Key: ARROW-2071
> URL: https://issues.apache.org/jira/browse/ARROW-2071
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Wes McKinney
> Assignee: Antoine Pitrou
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.9.0
>
>
> For some reason, recently each Python build has been taking about 15 minutes
> to run. I speculate this is due to VM thrashing caused by reduced resources
> on the Travis CI workers, related to the problem I fixed in ARROW-2062.
> We should experiment, but it seems like perhaps this can be fixed either by:
> * Reducing the size of the Plasma store on Travis CI
> * Disabling valgrind in Plasma tests
> The slowness could be caused by something else, though, so we should
> investigate (and have pytest report slow tests in the logs)
