! 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 "a good problem"
! 192: though.... </p>

! 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>
