Well, after all the discussion back and forth about FTP speed on the
Macintosh, I went out and did a few experiments. All of these were with
NCSA Telnet 2.3, with a release letter dated July 15. Make of it what you
may. Disclaimer - I am not speaking for Apple, your mileage may vary, etc.
Sun 3 -> Macintosh II, NCSA Telnet with NCSA TCP code -
4.4kbyte/sec ASCII, 4.9kbyte/sec binary
Sun 3 -> Sequent Balance (for comparison) (didn't have 2 sun accounts)
75kbyte/sec ascii, 212kbyte/sec binary
Sun 3 -> Macintosh II, NCSA Telnet with MacTCP, 8000 byte write buffers
35kbyte/sec ascii, 45kbyte/sec binary
Sun 3 -> Mac II, NCSA Telnet with MacTCP, 65536 byte file buffers
43kbyte/sec ascii, 45kbyte/sec binary
Sun 3 -> Mac II, NCSA Telnet, MacTCP, write calls commented out
(no disk traffic)
49kbyte/sec ascii, 48kbyte/sec binary
File write benchmark, Mac II with SC80 hard drive -
8000-byte buffers - 277kbyte/sec
30000-byte buffers - 452kbyte/sec
100000-byte buffers - 385kbyte/sec
[note - I'm not too confident in this benchmark, especially the
452kbyte/sec figure. ]
