AW: How do you handle the poor performance of LC 7?

[Richard Gaskin]

Thanks for sending your stack to the team.  Please let us know the outcome.

And thanks for posting that handler.  Mike and Richard already hit on 
the only two items that come to mind (sorting and filtering), but I'm 
curious:  How does performance look if you comment out the call to 
xSortListe?

I wish I had time this morning to run some benchmarking between a loop 
through an array as you have here and a filter on a pre-sorted list, but 
my hunch is the latter would take care of a lot of that performance for you.

If you have time to run a quick benchmark on that handler with and 
without the xSortListe call commented, I would be very interested in the 
results.
