I *love* questions like that, because I can immediately respond back with
"well, that depends; did your sysadmin configure rfc1323 extension support
in your TCP stack?  Is SACK enabled?  What about window scaling?  Does your
OS do dynamic buffer tuning for TCP, or are the values locked in at start
time?"

I'm not so sure someone with only 2 years experience would know that.
