Optimal read buffer size?

Hello:

I find that when I write network code, I never really know how big I should make the read buffer. Some protocols have only short packets so I usually have a pretty small buffer, or only read in one packet at a time, but if I'm reading in a very big packet like a mult- megabyte resource download that I'm writing to disk, is there a sweet spot that requires the fewest read calls and doesn't waste (much) memory?

Thanks,
chaz
