Hi Massimo,

Hey Steven,

Hi Massimo,

do you have any opinion about this?
any idea?
any suggestion to improve datarates?

Just the usual.  Provide us with specific details rather than general
comments.  This means a copy of your inetcfg.ini, in this case.

Follow the tuning suggestions from the os2world thred.  Log setting and
results as you go.  Do not depend on your memory.

Test both with a without ijfw and log your results with various ijfw
settings.  Even with the new driver ijfw still seems to impact outbound
traffic more than one would expect.

Steven

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
