The results of a netstat on z/os showed me that while the actMtu is 8192
while under BSD Routing Parameters it shows an MTU Size of 00576.
Question: Does this mean z/OS tcp/ip is breaking 8 K packets into 576 byte
units each with its own header? Shouldn't the MTU size under BSD Routing
Parameters be higher?
I am doing point to point data connections via hipersockets to talk to DB2
on z/OS, so there should be no routing going on. I'm just trying to figure
out if this adversely impacts my hipersocket performance.
