staggeringly similar story.
did a bit of coding for a client who sold a business app on either Elonex or Apricot PCS. yep DOS days of course.
"Does anyone buy the Apricot" I said'
"Yep its ten times faster"
He proceeded to demonstrate with much whirring of floppy disks.
I was puzzled, Processors and speeds wer identical.. then I had a thought. Sho nuff the elonex had in config.sys :
on the apricot they were much higher.
I edited the file rebooted and said 'now try it'
Nobody likes a smartass do they?
