Re: Objectconnect speed

OBJECTConnect uses SNADS and SNADS is de-tunned if you will so to be a 
background task for things like mail, spoolfiles and not high speed 
transfers. OBJECTConnect is convenient in that it creates the savf, saves 
the object(s), transfers them to system #2 and reverses the process all 
with 1 cmd.

If you are good at writing batch FTP code and using rmtcmd you could write 
you own simple program to do the same and use FTP as the transport.

Overall make sure that under CFGTCP that the "Maximum transmission unit" 
under interfaces is set to   *LIND and 
the "Maximum transmission unit" under routes is *IFC and the lind  SSAP 
Frame Sizes are 1496.

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?
