Hi,

I reported this in #117, but as that one is currently closed, lets move it here.

When having the plugin installed, and no project loaded, the CPU seems to be excessively used. The culprit is in one of the plugin_host threads of sublime_text.
Tracing the thread, it shows lots of activity in the virtual env, lots of the Python modules are accessed, as well as the package configuration files.

This makes my CPU usage on my i5 laptop spikes 12-25%.
