Actually, thats > probably a good tradeoff for 13 disks.. Same goes for the X86 dist! > ....something to sleep on I used Kermit a week ago to load 81 files of 240640 bytes each (about 19.4MB), and it took 3hrs 4min. These were chunks of a .tgz file, compressed. If your Kermit isn't up to date with long packets, sliding windows and settable control code prefixing, upgrade now! The computers: A Sun IPC sending via telnetted Cisco term. server connected at 38.4 kbps; a 486DX33, 8MB, FreeBSD-release, sio tty driver at 19.2 kbps, IDE disks. Kermit 5A(189) at both ends, as follows: 3000 byte packets 3 windows carefully tuned control code prefixes no eighth bit prefixing block check 3 RTS/CTS flow control 1742 file cps efficiency 91% Modem and phone line: Connected to the FreebSD system at 19.2 kbps, an AT&T 3820 modem, running V.32terbo (19.2 kbps) + V.42bis. A *LOCAL* call to the Sun (through a terminal server). I didn't run at 38.4 kbps because experience showed me I lose. Since then I downloaded another bunch of split .tgz files for XFree86, about 12.4 MB. Kermit reported 1hr 57min, 1769 cps, 92% efficiency. Since that time, I've catted and ungtarred all of it, with no errors. I did both batches overnight. At those rates, I'd quite willingly download 48 MB of compressed .tgz file chunks overnight. At about 6 MB per hour, a good night's sleep.
