Steve,
It is safe to say that the XML has many more characters. I have taken the
same purchase order transaction set and printed both the X12 and XML
versions. The X12 version printed on half a page, the XML took seven pages.
I am told, however, that the XML compresses very well (e.g., zipped format),
and the transmission time is reduced accordingly. As Dick pointed out, your
transmissions are small enough that you should easily meet your time
constraints.

Steve,
I don't have empirical numbers on XML versus EDI( X12 or EDIFACT), however I
do have empirical numbers on the VAN's versus the Internet. Certainly the
"language" will impact the size of the data being transmitted, which will
affect the performance, but for smaller transmissions the difference would
be negligible.
Let me know if you would like to know more about our findings.

Subject: The need for speed: XML vs. Internet EDI
Hi All:
I would like to know if anyone has done any actual benchmarks in this area
of comparing the speed of XML to EDI on the Internet. Is there anything
inherently faster/slower about XML?. I am not talking just transmission
speed, but point to point (DB to DB).
We are working on sending messages to satisfy service requests, some of
which are very fast turn around: 4hrs, 2hrs and soon to come 1hr. That is
from the time the request is committed to our database until the time the
replacement part arrives at the customer's site (scope: worldwide). As you
can see from this, time is of the essence. We would like to see a 60 second
or less turn around in message delivery. 20 - 30 seconds would be great.
That is the time from our DB commit to the time the message arrives at the
remote shipping depot - which is run by a third party carrier that
warehouses our parts. Protocol: HTTPS.
Time includes: triggering the send, extracting the data, mapping the data,
encryption, sending, receiving into the DB at the other end.
Currently our EDI (via VAN) takes about 5 minutes (could possibly be
trimmed) to deliver to the VAN and about 5 minutes for the VAN to deliver to
the trading partner. Problem is that the VAN only guarantees one hour
delivery. This makes the time to TP a possible 1 hour 10 min instead of the
usual 10 minutes. This ruins the 1 hour support and cuts too deeply into
the 2 and 4 hour service. Even 10 minutes cuts deeply into a 1 hour
delivery promise.
I don't expect transaction size to be an issue. Typical EDI transactions
are around 1K. Even with a 50-to-1 verbosity ratio sending 50K is not a big
deal. Current benchmarks on our file transfers is 11 seconds per meg.
Thanks for any real world data you can send me or ideas you may have on
this.
Steve Bollinger.
