  175: </ul>
  176: 
  177: <p>A lesser machine can be used for toying around with LON-CAPA (LON-CAPA will
  178: run for a single user on most any machine). </p>
  179: 
  180: <p>LON-CAPA servers experience significant peaks of activity before a homework
  181: submission deadline. To support these critical peaks of activity, it is
  182: strongly advised that LON-CAPA machines fit the above recommendation. </p>
  183: 
  184: <p>If thousands of students start accessing the box as a web server... well you
  185: may want to consider more options. The design of the LON-CAPA system is to
  186: naturally and transparently load-balance on multiple computer clusters. So, a
  187: simple solution for running an entire college campus is to just have an adequate
  188: plurality of LON-CAPA servers rather than a single, particularly monstrous
  189: server. </p>
  190: 
  191: <p>We like to think of high web server usage as &quot;a good problem&quot;
  192: though.... </p>
  193: 
  194: <h2><a name="_Toc421867154">Additional Information on LON-CAPA Server Hardware
  195: Requirements</a></h2>
  196: 
  197: <p>LON-CAPA works nicely (for development purposes) on a Pentium II, 20
  198: gigabytes of hard-disk space, 256M RAM, and 400MHz. The consensus is though,
  199: that this may only be adequate for a class of a dozen students. </p>
  200: 
  201: <p>If you are making a serious investment, you should join the LON-CAPA mailing
  202: list by visiting http://mail.lon-capa.org/mailman/listinfo/lon-capa-users. By
  203: posting to this mailing list, you can learn about the solutions have worked for
  204: others. </p>
  205: 
  206: <p>LON-CAPA works on any Intel-based RedHat-compatible hardware. Unlike other
  207: e-learning software systems, it works comparatively well on dusty old crippled
  208: machines without much RAM or processing. </p>
