I would like to know if JIT makes Miami faster or if
the bottleneck is somewhere else.

<if JIT makes Miami faster> JIT makes miami faster
But the troughput stays the same . So if u have 28K8, the
troughput stays 28K8 and there are coming no more bits
then your 28K8 modem allows. So in fact the miami(program) speed has nothing to do with the troughput of your socket/pipe or whatever u will name it.
-Miami can handle "any" speed. Miami is a tool that allows u to make a connexion with the WORLD of Internet
I have a ADSL connexion with Miami and my nextdoor neighbour has a 2 Megabit connexion with Miami.
Hope this helps

ok my fault.
LAN-Speed is what I ment.
I have 1-1,5 Mbyte/s at the moment when using ftp

It's the same here, only about 1,25 MB/s when using ftp. I've heard from several people that there's a problem with Miami, so if you want to have higher speed for now you'll have to use Genesis/AmiTCP. (I haven't checked the speed with Genesis myself but I will soon)

Miami is slow when using Sana-II drivers, I have never heared a technical description...hence the existence of MNI (Miami native drivers)

If you want fast and SanaII ... use AmiTCP

I could make some tests but here is what I did on the show floor in AmiWest:

Wireless 802.11b <> Mac 1GHz G4 Tibook Airport <> Pegasos G3-600 100Mb/s ethernet on MiamiDx 1.0c using via_rhine.device

I copied 2 x 700MB files over this LAN link between the Mac and Pega at a max rate of around 1.25Mb/s accoring to Miami stats....this was using JIT.

Of cours...direct to the internet speeds were limited by wireless bandwidth.

I could make the same measurement using non-JIT if someone really cares to see the result.
