My statements on kermit were based on performance tests I carried out
personally. All protocols were tested out of the box. I stand by the 2-3
time performance estimate as it is what I saw with my own eyes.
I note the article you mentioned shows kermit to have superior performance
but the fact is I did not see this when I tested it. Which was a pity as
it was otherwise very convenient to use. The article goes on to suggest
that various implementations of Kermit were poor, which i do not doubt,
but I was using real Kermit on a unix platform on both ends.
The article itself mentions that Kermit takes care of stability first &
speed second. This statement I agree with 100%. I found Kermit to be
very reliable, just not fast :)

I did prefix my statement with "Before ppp/slip" :)
: yourself up to date before giving advice in public:
Why? Have any of the mentioned protocols (X-Modem, Z-Modem, or Kermit)
been redrafted since then? They're still the same protocols they were.
You canna change the laws of physics :)
