[jira] [Commented] (ARROW-1861) [Python] Fix up ASV setup, add developer instructions for writing new benchmarks and running benchmark suite locally

["Antoine Pitrou (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1861?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16346791#comment-16346791 ] 

Antoine Pitrou commented on ARROW-1861:
---------------------------------------

Is there a point in testing so many different sizes in the benchmarks? Intuitively I would test two different sizes ("small" and "large" e.g. 10 and 1e6). More sounds overkill

> We need to start writing more microbenchmarks as we go to prevent unintentional performance regressions (this has been a constant thorn in my side for years: http://wesmckinney.com/blog/introducing-vbench-new-code-performance-analysis-and-monitoring-tool/).
