I have done that. However, one of the most profound features of our product is to support 10k connections concurrently. If I use a large buffer, it would consume GBs of RAM. (and this is 32-bit process thanks to Borland/CG/Embarcadero). If I use a small buffer it would mean a waste of resources as the benefit is small. I think I will rely on Windows caching for this. Or maybe play with it within my test app...
