                            <comment id="1059570" author="milkie" created="Tue, 13 Oct 2015 20:37:13 +0000"  >&lt;p&gt;Can this be resolved?  The combination of the electionTimeout change plus the parallelization of the sharding suite has made it difficult to diagnose the slowness that was formerly present.  Notably, even before those commits, I could not reproduce the slowness on my own machine, so I was beginning to suspect something specific to the builder that was running the tests (the slowness was only apparent on the generic &quot;Linux 64&quot;-flavored test runners.)&lt;/p&gt;</comment>
