Re: APPN vs. TCP/IP performance

Opinions..... you know what they are like.
My experience has been that your boss is correct.  The IP connections that
I have been associated with are generally much faster and much more stable
than their SNA counterparts.  The is especially true of dial up TCP/IP
(such as SLIP to thru a RAS server).  I generally get sub second response
dialing TCP/IP to my AS400.  I could never make the same claim using SNA.

Also, AS400 to AS400 connectivity (over a LAN adapter) is also much faster,
FTP is much faster than SNADS for moving files between AS400s.  

Also, IBM just announced TCP/IP over twinax support (in v4r2), so it is not
hard to see what direction they are heading.

Just me opinions.
