XForms performance and scalability
Locked
 
|
Hi All,
Does anyone have any real user experience or facts concerning how well XForms will scale and perform, particularly in relation to Orbeon? The reason I ask is that different XForm implementations seem to provide different performance ratings, so I'm trying to collect others feedback.

Hi Josh,
PresentationServer provides platform on top of which applications are written, and when we ask about how PresentationServer scales, we want in fact to know how an application written on top of PresentationServer scales. But the variation between applications is so great that we have found that it was impossible to come up with any generic statement. Since the question comes up on a regular basis, we try to address it in the FAQ: http://www.orbeon.com/ops/doc/home-faq#performance-numbers Alex On 4/9/06, Josh Joy <[hidden email]> wrote: > Hi All, > > Does anyone have any real user experience or facts > concerning how well > XForms will scale and perform, particularly in > relation to Orbeon?

Thanks for your reply.
Does anyone have any sort of design patterns, some Dos and Donts, recommendations, etc related to XForms? Simple scenario, let us suppose the company I work for is investigating using XForms. Our website will receive anywhere from 100k to 500k visitors a day. What should I be worried about? What controls should I favor over other controls? Etc.... I think these are very important questions. Initially I was under the impression Xforms lack of adoption was due to poor browser support, though for Enterprise applications in relation to /performance, scalability, and maintainability/ is XForms a viable choice?

Josh,
If you are going to get 500K visitors a day, surely choosing the right technology will warrant that you spend some serious time developing a prototype and doing your own performance testing and tuning on it. I wouldn't base a final decision for such a large site / application just on second-hand information, however good or bad. We obviously think XForms is a great choice today and will have an even brighter future tomorrow, but the answer in your own case depends on so many factors that it is hard to give you a good answer out of thin air. XForms is likely to be more resource intensive than, say, a simple, compiled JSP-based page. The OPS XForms engine uses XPath evaluation, maintains XML documents to keep state, etc. It does quite a bit of processing to transform an XHTML+XForms page into an HTML+Javascript page sent to the browser. But there is performance tuning that can be done. The result XForms transformations could be cached if the pages are static and have to be served on a web site's home page, for example. As a developer, you can also reduce the number of XSLT transformations to 1 or even 0 if you don't want a theme stylesheet, and optimize the epilogue pipeline to be as minimal as possible for your needs. Finally, the OPS code itself could certainly benefit from optimizations. -Erik Josh Joy wrote: > Thanks for your reply. > > Does anyone have any sort of design patterns, some Dos > and Donts, > recommendations, etc related to XForms? > > Simple scenario, let us suppose the company I work for > is investigating > using XForms.
