Most likely the slowdown is while Aspell is coming up with suggestions.

What version of Aspell are you using?  If you are still using Aspell 0.50 
you should upgrade to 0.60 as there is a large speedup in the suggestion 
speed (see http://aspell.net/test/cur/).  You can also try setting the 
suggestion mode to "ultra".
