   For full-time, classroom usage, an adequate LON-CAPA server
   should be/have:
   </p>
   <ul>
   <li>a multiprocessor machine,</li>
   <li>a CPU speed of 1 gigahertz,</li>
   <li>a gigabyte of memory,</li>
   <li>and at least 40 to 80 gigabytes of hard disk space.</li>
   </ul>

   A lesser machine can be used for toying around with LON-CAPA
   (LON-CAPA will run for a single user on most any machine).

   LON-CAPA servers experience significant peaks of activity
   before a homework submission deadline.  To support these critical
   peaks of activity, it is strongly advised that LON-CAPA machines
   fit the above recommendation.

   If thousands of students start accessing the box as a web server...
   well you may want to consider more options.  The design of the LON-CAPA
   system is to naturally and transparently load-balance on multiple
   computer clusters.  So, a simple solution for running an entire
   college campus is to just have an adequate plurality of LON-CAPA
   servers rather than a single, particularly monstrous server.

   We like to think of high web server usage as "a good problem" though.. :)
