Ok well i thought i'd try a different approach, so what I'm now trying is
appending 50,000 lines from the collection to a stringbuilder, and then
writing that entire stringbuilder to a file.
However, look at this log:

complete
21/04/2006 14:23:59: Building String Start
I clear the stringbuilder between appending to the file using this code:
sbFileContent = New StringBuilder
However, there's still obviously a big slow down, why is this?
