Large data sets?  So you are saying that 512-byte packets with no  
windowing work better?  Bill, have you measured this?

Time to download a 100mb file over HTTP and a 100mb interface: 20  
seconds.
Time to download a 100mb file over FTP and a 100mb interface: ~7  
minutes.

And yes, that was FreeBSD with the old version openssl library that  
shipped with 6.3.
