Go to APPC controller descriptions - on both systems - and tweak LANACKFRQ and LANMAXOUT. Default value *CALC is too conservative. You can't get really large frame on Etherner, but make sure you are using the largest value. Also try to increase pacing value in APPC mode used.

Recently I timed the movement of a single 5GB physical file and got barely 5Mb/sec speed. The sending machine is an S20 4-way at V4R2, the receiving machine an 820 2-Way. Neither was doing anything at the time (CPU <5% on both). The connection is pure SNA over Ethernet. The Ethernet cards are both 100M and each reports a 100M full duplex connection. Both are connected to the same Ethernet Switch which reports virtually no traffic utilization. Even wrksysact shows the send and recieve tasks using virtually no CPU and no I/O. I'm going to try again with performance tools running but..... This is pretty sad performance with this kind of horsepower. Any ideas or similair experiences? Tweaks to the LIND or CTLD maybe? - Larry -- Larry Bolhuis Arbor Solutions, Inc.
