libcurl (or anything else using select) probably isn't the best choice
for benchmarking, but i do see one major flaw:

dev_null() printing stuff out will be a major drain on performance,
especially with that endl flushing the stream... consider having it
just return size*nmemb. if you must print something, make a static
variable and only print when (++var%500) == 0.
