Wes McKinney commented on ARROW-646:
------------------------------------
[~cpcloud] [~leif] I marked this for 0.3 -- with the rampant conda /
anaconda.org timeouts, if we can cache our conda tarballs using Travis CI
caching we may be able to both speed up builds and reduce flakiness. I think
this may involve changing the conda cache directory to be someplace other than
the miniconda/ install in
https://github.com/apache/arrow/blob/master/ci/travis_install_conda.sh#L27.

> The unpacking of freshly downloaded conda packages makes up significant time

> 1min to 14s.
