Hi Micahel,

Server -Windows XP with IntelPro1000/MT running on a 10Mbs shared hub,
http_fs (mini http file server) file read from disk (probably cached)
Client - Apple IIgs runing in 8 bit mode - ProDOS, Contiki OS, ethernet card
based on the cs8900a, frame size tuned to 1400bytes
Http download  of a 140KB dsk image to memory (no write to disk) avg about
40K bytes per second.
Performance drops as window size is decreased
