iperf for 68k / System 6?
Posted by: rieSha. on 2020-10-22 11:20:59
Hi,

admittedly, the title is a bit clickbaity. I’m looking for a System 6/7 safe software, that measures DDP/AppleTalk performance between 2 hosts. As I’m playing with ATrouting and RAS, this would really help me debugging stuff.

I've never heard of such software, but I wouldn't be surprised if something like that existed.

Transferring a large file is a good way to measure performance.

For System 7, Speed Double 8 when installed as a full package will display file transfer speed, although I can't speak to, the, uh, veracity of those measurements. I've only ever done this on PowerPC though. (overall the main selling point of SD8 is to replace the 68k emulation code so it's primarily PPC targeted but the other functions it does have might work on PPC, there's also a server component which I've laid eyes upon but never tried to use.)

Unfortunately, I don't believe it records a history and calculates a final average overall speed. That might be doable with IP-based software using MacIP, but that's very much entering into a different era and sort of getting into a different set of potential requirements.

Are you writing your own software that uses Appletalk? Why not record the value of Ticks, then make an echo type request using DDP, and then when you get the response back, compare with the present value of Ticks?

No, I’m setting up a non-trivial AT network, with RAS and the like, step by step. I thought that I’m not the first guy running an AT network with more than 3 hosts, so that someone for sure wrote some networking debugging tools beyong "DDPing" 🙂

"NetMinder LocalTalk" is a reasonably decent LocalTalk packet sniffer, which I've used quite a lot in debugging my own LToUDP implementation.  It's available on the Garden.  For EtherTalk I mostly fall back on switch port mirroring + Wireshark, because I am not a masochist.

I don't know of any bulk performance measuring tools analogous to iperf though.
