As a suggestion from Eric I also tried X=A000-EFFF to completely disable
UMBs. But that didn't do.
It only works if I completely disable EMM386.

That shows that the error is not be looked for in HIMEM.

O.K. Then let us forget the benchmarking.

I had a try on some other PCs that morning.
I discovered that EMM386 works much better than I expected.
I did use HIMEM/EMM386 until let's say the middle of last year. At this
time I felt it would be better to use Jack's and Uwe's files because I
really was frustrated about EMM386 crashing the whole machine very often
when loading other device drivers in UMB.

But today it wasn't like this, I must say
The only thing I discovered so far is, that EMM386 has got problems with
the Microsoft network client.
On many machines everything worked fine and till now I only discovered a
Pentium 4 2,8 GHz with onboard Intel Pro 1000 ethernet card were the
network client stops responding while trying to get an ip address over DHCP.
