         You could start with your file system.  I've got all web/minivend 
stuff operating on a separate drive, isolated from the OS.
         Page and Search Caching helps a lot.  (basically, an 'on' or 'off' 
directive in  your config)
         Building an index of your products for fast binary search helps 
greatly, especially if you find the best field to build the index 
by.  (Personally, I used the first/code field, as most of my access is by 
item code.)
         Lastly, using efficient minivend scripting/perl coding can shave 
some seconds.  It is a challenge sometimes to develop code to achieve a 
complex task (especially when it is not found in examples or the demo - 
such as 'shoppers who bought X also bought Y'...) however, it is more of 
challenge to make that code efficient and faster.

         You've got a perfectly capable machine, it should not take 20 
seconds to display ANY page.
