RE: HP 75 and the PIL-Box
Thank you Jean-Francois, thank you Christoph for joining our discussion!

Fortunately I finally succeeded in gaining a high transfer rate of almost 400 Bytes per second - and got closer to the root of all evil:

I did the following tests:
Just Emu71Win and ILPer v.1.43: Copying of a 1.7 kByte file took less than one second!
Then my favorite setup:
My HP 75c linked to the PIL-Box, ILPILBox (!) running on my Win7-64 machine, (FTDI driver 2.8.30, latency timer 1 ms, 115 k baud rate, IL scope disabled )
linked to ILPer by TCP/IP.
I like the flexibility and expandability of that concept. Result: More than two minutes for copying of a 7k file. :-(

Finally I omitted the ILPILBox and connected ILPer directly to the PIL-Box.
Result: Less than 18 seconds for the same file!

Christoph, how can the additional TCP-IP traffic have such a desastrous impact on the overall performance? Since the pure combination Emu71Win - ILPer, also linked by TCP/IP, is extremely fast, it seems to be a problem with ILPILBox ( Version 1.1 ) ?
