<p class="MsoPlainText">I had an old MapServer application running on a production machine. It used IIS and it ran fast. I upgraded the application on a development machine. I switched over to Apache (for MapCache) and the new application ran fast on my
development machine. We moved the new application onto the production machine. It does not run fast.

<p class="MsoPlainText">I am trying to figure out why MapServer 5 would run fast under IIS, while MapServer 6 under Apache runs slow. There are a couple possibilities, if anyone could confirm the following as a problem, or has a solution please let me know<o:p></o:p></p>
