Hiya Richard,

long time no banter (been keeping quiet my end)

it wasn't 2 000, it was 20 000
it's IO intensive where VM wins out, and only when you can counter the terminal
IO wait PC archetecture suffers from.
for a processor intesive task you'd go the bare metal.

what's the smiley for biting one's tongue?  I can understand where the
commenters are coming from.
