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:

21/04/2006 14:09:06: Building String Start
21/04/2006 14:09:14: appended 10,000 lines to the stringbuilder
21/04/2006 14:09:39: appended 10,000 lines to the stringbuilder
21/04/2006 14:10:20: appended 10,000 lines to the stringbuilder
21/04/2006 14:11:20: appended 10,000 lines to the stringbuilder
21/04/2006 14:12:36: appended 10,000 lines to the stringbuilder
21/04/2006 14:12:36: append of 50,000 lines to file from stringbuilder
complete

21/04/2006 14:14:05: appended 10,000 lines to the stringbuilder
21/04/2006 14:16:00: appended 10,000 lines to the stringbuilder
21/04/2006 14:18:36: appended 10,000 lines to the stringbuilder
21/04/2006 14:21:18: appended 10,000 lines to the stringbuilder
21/04/2006 14:23:58: appended 10,000 lines to the stringbuilder
21/04/2006 14:23:59: append of 50,000 lines to file from stringbuilder
complete

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?
 
sorry this is a mistake - please delete - this was meant to be a reply to an
existing thread
 
Smth wrong with algoritm, I suppose.
Could u show the code?
