alt Hacker NewsDo you have a good sense of what alllowed you to improve it so noticeably? Maybe fundamental design errors in the original, more modern algorithms available to you, or knowing where to skip (or remove from the hot path) functionality that goes rarely or totally unused?
Our family Mac was the first machine I loved. Unfortunately I never got to use with so much as a modem, so I have no first hand experience with using MacTCP.
I can’t pretend to be an expert on the TCP/IP protocol but I asked my agent for its methodology. It says: smarter ACK handling, bigger TCP windows/segments, better retransmission discipline, an ASSM checksum routine, and ditching malloc for fixed memory space were some engineering decisions it made that lead to better performance.
