RE: IFS Performance issue

Also, change your TCP interface to use *LIND for the Max Transmission
Unit to make sure you're using the largest acceptable packet size.  

CHGTCPIFC INTNETADR('someipaddress') MTU(*LIND)

For that matter, check your Ethernet line description.  You should
probably be using 1496 as a frame size.

CHGLINETH LIND(somelind) MAXFRAME(1496)

Finally, how many downloads are running at the same time and is your
system LAN or WAN attached?  WAN attachments will definitely have a
performance hit.

Sometimes it's the *FULL duplex setting that causes more troubles than
doing anything good. Try *HALF  duplex and turn off auto negotiation on
the specific port of the switch, if it is manageable at all. Recommended
setting for 100 MBit Ethernet has been *HALF for the AS/400 for many
years, I don't know if this is still true with the newer controllers in
a model 270, but it is worth a try. There are still some combinations,
where auto neg. won't work. Famous combination is cisco routers with
dlink switches ...
