[JBoss Seam] - Re: JBoss EL performance vs Sun EL
by lowecg2004
Are you able to post some actual code that demonstrates these performance issues: (beans, facelets etc)?
In addition to all the EL parsing, reflection, etc. the EL calls will probably be subject to several layers of interception. Do these show up in your timings?
I know you've run a profiler on the session and currently all fingers point to EL, but another thing to consider is that there are certain cases in IE where the browser itself is incredibly slow at rendering tabular data. I had a JSF app that rendered incredibly slowly. After profiling, I saw that the response was generated in a fraction of the time that I was witnessing. Even after saving the generated HTML to a file and opening up in IE it generated slowly. Opening the same file in Firefox was very quick. Like I said, probably not directly relevant here, just something to look out for.
