At the time of installation, it asked if I want to use
EAServer for the Appeon Server or .NET. I selected .NET, and
my application is like very very slow. For example, the
window loads in about 2 minutes.
I have tried all possible suggestions by Chris Pollach
(Thanks to him), but it does not make any difference at all.
The same application when deployed with PowerBuilder .Net
forms work fast, so it is not the application problem.

My question is that, is there any performance difference if
using the .NET server or EAServer? Could it load faster if i
use EAServer?

Thanks.

Hi Jay;

Appeon has two architecture models that it supports - either J2EE or
.Net. If you install the J2EE route - you can install to jBoss, Weblogic,
WebSphere ... or EAServer (Sybase's J2EE) offering. Either way, Appeon
functions basically the same. However, I am very puzzled with your
performance findings as its completely the opposite of what I have found
using both the J2EE & .Net versions of Appeon versus Webforms in real world
web conversions.

In fact, speaking with Appeon, Emerald City software and Accenture (both
who converted their existing PB products to the web via Appeon) have
commented to me that the .Net version seems to be slightly better in
performance. In my detailed analysis as of late - I can pretty much say that
my benchmarks concluded that .Net was just as fast as the Weblogic deployed
version of three systems I converted as I ran some pretty heavy test loads
through. BTW: all three systems do some pretty wild database I/O in places
over to Oracle 10g & 11g servers.

So to answer your question in broad terms - I would highly doubt that
deploying to EAS (aka J2EE) would be beneficial unless <big caveat here!>,
you have some weird IIs or .Net configuration(s) that are working against
the Appeon server (which s basically a .Net helper inside of IIs).

FWIW: Wow, you are certainly coming up against as series of strange hurdles
here! The other problems facing you though are: 1) Sybase has declared that
they are *no longer* enhancing Webforms since PB version 11.2; and 2) Sybase
has just informed one user group that they are no longer enhancing EAServer
(one of my ISUG members just emailed me the other night about this one) and
that EAS 6.3 would probably be the *last* version (need to get this
substantiated by Sybase though)!

Hi,
true thing is that Appeon is faster - and also slightly architecturally
different - than Webforms (which is also - as stated by Chris -
dismissed by Sybase). Besides, Appeon .NET is on average 20% faster than
J2EE. I have run it on basically every J2EE servers and must confirm
.NET is faster. However, overall speed is not the only parameter for
choosing .NET, many interesting features perform better (or only) on
Java platforms.
As far as your app is concerned, please note that Appeon porting is
everything but just blind "convert&run". Many performance issues can be
tweaked after deployment. What I mean, you are certainly able to run
successfully your PB app just striking the deployment process, but it is
advisable to go further. A Web app is very different from a client
server app and - just to name a few - server calls must be smartly
monitored and reduced. Appeon provides an excellent reference guide for
performance troubleshooting with techniques for optimizing many PB
coding issues. A good starting point for you, before digging into this
amazing guide (which is worth to read just for Web programming advices)
is the Appeon performance analyzer tool. It tells you step by step the
amount of time taken by the deployed app and you can understand the
origin of slowness (personal advise, make your best to reduce the time
of RPC - remote process calls). A correctly tweaked Appeon application
can run even faster than the corresponding client server version!
Best,
Marco
