	Which one of these values are you looking at:

                  total pools:          274
          total buffers in use:         4285

                total memalloc:     61349016
                 total memfree:     61348461
               memalloc in use:          555
             memalloc failures:            0
              memfree failures:            0
           memalloc high water:          724

	The only time I see a performance problem is when I've
accidentally left some combination of: radif, pppif, etc running when I've
closed the telnet session. That seems to make the Max real sluggish.
