There is no performance gain in buffering an in-memory output stream. You  
will likely see a tiny decrease in performance instead.

I am pretty sure that you won't notice any difference, but what you can  
try is to start with a bigger buffer size (e.g. 1 MB) to prevent some  
copying of the data as it grows:
