 System Requirements  Hardware Recommendation
 -------------------  -----------------------
   
 It should be an intermediate-to-high-level  For full-time, classroom usage, an adequate LON-CAPA server
 performance workstation computer.  A ballpark suggestion  should be/have:
 is that it is PentiumII or greater, has 20 gigabytes of  
 harddisk space, 256M RAM, and 400MHz CPU processing speed...  
 Dr. Kortemeyer at Michigan State University can give a more  
 thorough response if needed (he has experience with setting  
 up high-performance web server clusters).  
   
 A specifically high-level suggestion is a multi CPU machine  
 (with a CPU speed of 1 gigahertz), a gigabyte of memory and  
 at least 40 to 80 gigabytes of hard disk space.  
   
 You can use a lesser machine for toying around with LON-CAPA (It will  
 install an run for a single user on most anymachine) but if you wish  
 to support students and you wish to support deadline crunches my  
 suggestion is to go with the above.  
   
 LON-CAPA will work on any Intel-based RedHat compatible  * a multiprocessor machine,
 hardware.  And, unlike other software systems, it works  * a CPU speed of 1 gigahertz,
 comparatively well on dusty old crippled machines without  * a gigabyte of memory,
 much RAM or processing.  I am just projecting the characteristics  * and at least 40 to 80 gigabytes of hard disk space.
 that make LON-CAPA nice to use without any unreasonable slowness,  
 and in terms of hard disk space, how to make it at least 5 years  A lesser machine can be used for toying around with LON-CAPA
 down the road, if not more.  (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.

   college campus is to just have an adequate plurality of LON-CAPA
   servers rather than a single, particularly monstrous server.

   More Information on Hardware and System Administration
   ------------------------------------------------------
   
   I find that LON-CAPA works nicely (for development purposes)
   on a Pentium II, 20 gigabytes of hard-disk space, 256M RAM,
   and 400MHz.  The consensus is though, that this may only
   be adequate for a class of a dozen students.
