Re: Objectconnect speed

["Alexei Pytel" <pytel@xxxxxxxxxx>]

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.

Subject:  Objectconnect speed



Has anyone experience with ObjectConnect and what kind of speed you can
get with the thing? 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?
