There are several files available from the following server for the fix related to “Slow” kickoff application launcher response.
After installing the necessary files, my symptoms with this issue abated. This was not an issue when using the default nouveau driver. I am using the nvidia driver via the methods suggested by leigh123linux at the Fedora Forums.
The nouveau driver does not provide glx direct rendering support. The nvidia driver does.
After the latest versions were installed and I rebooted my screen response became exceptionally quick.
