I was hoping to compile some speed ratings for different Amiga's, CPU, TCP/IP stacks for PCMCIA ethernet. Can anyone contribute?
Format
------
Amiga = (A1200/A600)
CPU = (680EC020@14 / 68000@7.09 / 68030@50 / 68060@66)
Ethernet = cnet.device / 3c589.device (variants)
TCP/IP = AmiTCP/IP, Miami, GENESiS, Termite (With version number)
Speed = xxxKbit/sec
I am not too sure on what the tests should be? Any suggestions? I was thinking some sort of loopback test so that no more variables are added.
Other speed tests involve FTP, but then you introduce FTP server and clients into the mix.

I have a somewhat ordered mess of tests done with ttcp (http://www.aminet.net/package.php?package=comm/tcp/AmiTCP_ttcp10.lha) collected here (http://www.megaburken.net/~patrik/amigabenchmarks/ttcp). They have a varying level of documentation, but I think you will find some interesting info there.
What ttcp does is that it measures the raw TCP or UDP performance to/from memory. So basically it measures the performance of the TCP/IP-stack+network-device-driver+hardware combo of your system, without inducing any protocol overhead of say a ftp client or similar.
The most interesting is the TCP performance, as that is what most software used for bandwith-intensive stuff like file-transfers uses. This also the top roof in performance you can expect of well/effective written software. For example smbfs (http://www.aminet.net/package.php?package=comm/tcp/smbfs.lha) will with larger blocks achieve just about the top TCP scores you get with ttcp.
I have posted some earlier regarding how to use ttcp, which you should find if you do a search on the forum.
Btw, very important to get good performance is to make sure you have good "multitasking performance" - exec.library, VBR, etc should be in fastmem for example if you have an accelerator. It also often doesn't hurt to have a good CopyMem()/CopyMemQuick() patch installed.

Very interesting. Some rather strange results. Nothing really in the 1024kbyte/sec range for the majority of tests.
I will be able to provide you with some results for A4000 A3640@25 X-Surf and AmiTCP / Miami / Genesis soon

amiga= a1200
cpu= 68060/50 (bliz)
ram= 192 mb
os= 3.9 bb2
ethernet= 3c589.device
tcp/ip= amitcp/easynet or/and miamidx
speed= about 300 to 500 kb/sec max
as i figured out the speed depends from the size of the files i transfer. biger file size faster speed.
