Network Adapter throughput question

OK, I transferred a 2mb elf through ps2link today and it ran up to around 400k/s, although I am not entirely certain that is accurate.

Is the broadband adapter based on some odd standard or is it 10/100? Anyone know what the max throughput should be (I mean actual not theory/spec of course - even if it is only tested with the linux kit Id still like to know).

I know it depends on compression and other factors (like hardware bottlenecks), but I am still curious as to why currently available FTP apps are only getting up to around 110k/s if it is a true 10/100 connect.

I finally have a compiler working right under Gentoo flavored linux and really was just wondering hardware wise if it would be a waste of time to try and optimize ftpd for better speeds or if that has been done to its fullest already.

The broadband adapter can correctly negotiate 10/100Mb modes.

However, that has absolutely nothing to do with the throughput it can achieve.

Maximum throughput available to an application is purely a function of two things :

1. The efficiency of the underlying OS and its IP stack.
2. The amount of CPU power available in hardware.

The 33/36Mhz IOP is *not* going to go anywhere near 100Mb/s, even if it negotiated to that rate. You are lucky if you can even reach 10Mb/s.

400KB/s is roughly what you get with current ps2ip, until someone steps up and shapes it up.
