as you know i've 2 servers here
same OS, same AN driver packages (11/2018), ACPI, Intel Xeon 4 cores 2,4Ghz, same mobo 
(SuperMicro PDSME+), same Injoy FW version, same fxwrap build etc..

from my server2 i get download datarates of about 7MegaBytes/sec and
this is quite good, i'd say good enough for a 100Megabit FTTC

from my server1 i get poor download datarates about 2.5MegaBytes/sec at best

on both server the networking/tcpip part in config.sys is this one:

DEVICE=C:\MPTN\PROTOCOL\SOCKETSK.SYS /GDT:256 /MEM:4096
DEVICE=C:\MPTN\PROTOCOL\AFOS2.SYS
DEVICE=C:\MPTN\PROTOCOL\AFINETK.SYS
RUN=C:\MPTN\BIN\CNTRL.EXE /SM 1024 /LM 720

CALL=C:\OS2\CMD.EXE /Q /C C:\MPTN\BIN\MPTSTART.CMD >NUL

DEVICE=C:\IBMCOM\MACS\E1000B.OS2 /A1 = E1000B2$ /V
DEVICE=C:\IBMCOM\MACS\E1000B.OS2 /A0 = E1000B$ /V

DEVICE=C:\IBMCOM\PROTOCOL\FXWRAP.SYS
