Yes of course!  But I would recommend setting "fast = super".  It's really
the best option.  "fast = yes" is for the mundane.  Also, keep in mind that
a goal of Cygwin-X is to run things as slowly as possible but to add Cygwin
specific flags and patches anywhere possible to allow people to configure it
in hopefully very obtuse terms to run more quickly.  Without this added
complication, just about anyone could figure out how to run the X server
easily, which would then eliminate the need for this list.  No one wants that!

In all seriousness, if you really think that your question could be a FAQ,
why wouldn't you start with the Cygwin-X FAQ?  For example, the answer to
your problem may come from the following entry:

<http://x.cygwin.com/docs/faq/cygwin-x-faq.html#poor-performance>

Or perhaps something else listed in the FAQ would prove helpful.  If not,
please read and follow the problem reporting guidelines found here:

<http://cygwin.com/problems.html>

before posting any follow-up.  It will help you provide some information
that may allow others to assist you in pinpointing your problem.
