You will get more benefit from changing this from half duplex to full duplex than anything else. You will be amazed at increase in speed/throughput when you change the duplex to Full.

Subject: speed diff ethernet half and full duplex
Attempting to ftp a 32 gig savf from a v5r4 system to v5r2 sys (I know...going the wrong way). Systems have no tape compatibility, and opposite sides of the country.
The v5r4 has 5706 ethernet 10/100/1000 linespeed=*auto, duplex=*half No weekend view of the switch & router.
The v5r2 has 2849 ethernet 10/100 linespeed=10M, duplex=*half
I can see that if switches support it, get the v5r2 machine set to 100M or *auto linespeed, and duplex on both.
Figuring 10 x faster xmit if linespeed increase, but any way to quantify the duplex part? What I can google (non-iSeries) says it's almost twice, but not quite..
Also - framesize 1496 on each.
After 12 hrs only 4 gig received (per netstat byte counts)
Jim
