Is this a memory issue?

Performance degradation so noticeable isn't likely to be caused by a 
shortage of memory, esp. with such small data sets.

You could test it by rebooting, opening your System Monitor to show 
available RAM, run the routine a few times and see if memory stays 
allocated beyond what would seem normal.

My hunch is that there's something about the loop that's causing the 
slowdown, perhaps a "repeat with i=1 to the number of lines" or 
something like that which doesn't scale well.

Can you post the portion of your code that seems to be affected?
