<p>On my system, at <a href="https://github.com/mlpack/mlpack/commit/3beb8909d027921af9dd779f931fdbddbce32c18" class="commit-link"><tt>3beb890</tt></a> (for the optimize_load_csv_00 branch), here is what I see:</p>

<pre><code>$ time make -j12
...
real    3m48.390s
user    35m11.996s
sys 2m2.216s
</code></pre>

<p>And for master (<a href="https://github.com/mlpack/mlpack/commit/81c14d9ec8250f8a2caaf1ac06c4be12fc5fd31f" class="commit-link"><tt>81c14d9</tt></a>):</p>

<pre><code>$ time make -j12
...
real    3m17.387s
user    28m39.476s
sys 1m27.144s
</code></pre>

<p>I'm going to see if I can try anything to reduce that...</p>
