[datatable-help] Merging where key is large

[mdowle at mdowle.plus.com]

Damian,
How many persons are there?
How many rows are there?
What is the 'hit' measured in seconds?
Please post some code as often it turns out to be something simple e.g.
we'd want to confirm you aren't vector scanning by using == in the i.
