RE: WebFacing application EXTREEMLY slow

Starting Implementing WebFacing was as follows:

1) First problem was converting the application in WebFacing.  No
conversionreport was generated.
==> after loading SP4, all seemed ok.  At first I didn't find it on the
IBM site. I was switching from 'Support' to 'Info' page over and over.
Then I tried the 'DOWNLOAD' option... Bingo...

2) Second problem was loading application into VAJAVA Test Environment.
It couldn't find the Servlets.
==> It appears I had to add the webpath to jsp/servlets manually into
VAJAVA TE!  This means that for every app to test, you have to change
this path in WTE!  I found this sollution in one of the newsgroups.

3) Next, I got a response that the WF-Level was not correct
==> I installed the PTF's (should have done it first, it's in the
documentation)

4) Finally, there were no errors shown but also no application screens.
==> I had to add the Virtual Devices to an Interactive Subsystem, but
this was not in any doc I have!  I found out about this VT's because I
was looking at the joblogs.
==> It seems one also have to add the libraries one by one to the jobd
linked to the usrprf.  We used to work with a generic value but this
seems to fail?

What's left now?
- What slows down the application when called in browser? How to detect
this?
- Where to find more info about AS400-side of WebFacing?  (i.e. which
librarylist is used)
- What are 'general' sysspec to use WebFacing?
  we have only one system (720) which is used by our employees for Daily
activity.  This system also has WAS3.5.2 running and a couple of Notes
Mail servers.  Which leads us to: This will be the reason that the
applications are so slowly.  But how can we be sure?

I don't expect the panels coming up as fast as green screens but this is
really too slow now.  At the current speed, the users will think they
haven't clicked a button correctly and do it again and again...

So, what was the solution that made your application work?  I don't know
enough about performance yet.  My first load of a panel is also
extremely slow - about a minute.  I'm assuming this is because of the
reason you mentioned.  Subsequent use of the same panel is noticeably
faster, but no where close to green screen response times.
