You could of course set the stringlists duplicate property to 'dupAccept' to
allow duplicates.
In terms of speed, I have used the TStringList quicksort code to sort about
40,000 strings in under 1 second. Each string consisted of 42 random
characters. This was run under delphi on a p166 with 64 mb ram and NT4.

When you sort a Tstringlist it only allows unique entries! hence your 1600
