John,
Since QP2 is end-of-day database I don't think if it is worthwhile for them to
put significant work into speeding this up by say 50%.
After all waiting 5-10 minutes every night is not a problem.
As for Jet - QP2 is probably using it only for fundamentals and store quotes
in other format.
Also to be fair with QP2 - I must admit that they store a lot more information
than AmiBroker in its own database, so this justifies somehow the amount
of time required to update.
Best regards,
Tomasz Janeczko
