<div class="moz-cite-prefix">So if I get this right, significant
speedup for rosmake could be achieved <br>
by replacing yaml.load() with yaml.load(..., <span class="x">Loader=yaml.CLoader)
</span>and <br>
yaml.dump with cPickle.dump<br>
<br>
Does anyone have the time to investigate whether this also gets us
significant improvements for any of the other yaml-bound packages
that we use?<br>
Such as:<br>
<br>
rostopic<br>
rosservice<br>
rosbag<br>
rosmsg<br>
rosparam<br>
roslaunch<br>
rospy<br>
actionlib<br>
dynamic_reconfigure<br>
rosdoc<br>
<br>
At least for rosbag, I seem to remember seeing complaints about
speed on answers.ros.org, that could of course be related to
something different entirely.<br>

I am happy to report that rosmake under Groovy (Debian install) is
now much faster. A stack that used to take 149 seconds (2 minutes
29 seconds) to build now takes only 22 seconds which is 6x faster
than before.<br>

If I am reading the bug reports correctly (<a
