+<p><b>Warning: Apache on NT has not yet been optimized for performance.
+Apache still performs best, and is most reliable on Unix platforms.  Over
+time we will improve NT performance. Folks doing comparative reviews
+of webserver performance are asked to compare against Apache
+on a Unix platform such as Solaris, FreeBSD, or Linux.</b></p>
