I have a confession to make. I accused the remote system administration tools at my work of regularly monopolizing the system resources every 10 minutes.
As it turns out, it was actually one of my favorite programs, Launchy. It seems that the default configuration for Launchy to rebuild its catalogue is 10 minutes. That is to say that Launchy will read a whole lot of files every 10 minutes. I believe that doing that was overwhelming my system to the point where it became unresponsive.
Part/all of this is my fault. I configured the catalog to point to some directories that contained lots of files. As a result, the catalog consisted of over 2000 entries. That's probably outside the boundaries for which Launchy was designed.
The way I worked around this hurdle is to set the catalogue rebuilding to manual. Another alternative is to define the scope of the catalogue to a reduced area.
Even after crushing my system performance. I forgive Launchy. It is an awesome tool.
