Server comments

[Jim Bodkikns (Dakotacom)]

   We really dont have load issues to speak of. Isnt modern hardware just 
wonderfull. :)

   Most of our systems are disc bound. Typical database of 3 to maybe 10 
million records. (reservations and related info) Having a number (could be a 
dozen at once) reservation agents doing 30,60,90 or 120 day forcasts really 
hits the disc subsystem. (Normally cached SCSI raid - GDT at this point). 
Some latency is expected by users when they understand that the function 
they are performing is 'extreme'. (Fraction of a minute in the worse case).

   Mainly, its what is installed and what we have to do to install it that 
takes the time.

   BTW, sounds like you are getting just amazing service from your server.
