Re: Pushing XML out to a browser request

It all depends ...

I have SQL REST based CGI services that generates XML in 0.02-0.04 seconds
on the server,
the roundtrip on the external internet browser is about 71 ms

One second doesn't seem to be bad for response time.

If you're writing to a DB and they are reading it maybe all the channels
are slowing it down a little.

Would have to know more about the plumbing sequence but it sounds like
you're writing to a DB entry and then they are reading it ?

Why not create an RPG based XML URL requestor instead so the XML
response is immediate to the java app from the HTTP call to the RPG app. No
DB or clob interaction needed.

Then again I don't know the app architecture and 1 second response sounds
good to me :-)

subject: Pushing XML out to a browser request

In a nutshell, we have a back end home grown RPG ERP system with a J2EE
based dealer extranet on top. Part of the function of the dealer interface
is the management of warranty claims. The browser requests claim
information from the back end and the back end produces an XML document in
return. This works great - except - our web comrades complain that it takes
over a full second to get the XML back. They do direct SQL hits to the DB
and get results in a tenth of the time - so they complain. Do you know of
anyone who has struggled with response time related to creating XML via RPG
and passing it back to a web interface? We don't know where the bottleneck
is. It might be on the browser side, but we can't seem to isolate it.

If anyone has insight about this, I can provide more details to help you
answer.

Many thanks!
