I have some questions about performance too.
We have run a
J2EE style setup to render pages for our PlayStation games. So we have a fairly high concurent user count (~50,000 concurrent users is not uncommon).
About a year and a half ago we switched from a straight JSP approach to using Cocoon and XSLT. While it was an elegant solution the performance was about 25% of the page count we could render with the straight JSP solution so we had to rip all the Cocoon stuff out. Now we use JSP with taglibs.
JSF sounds interesting because we render HTML pages (for the PC side) and a custom markup language set of pages for the PlayStation side. So it sounds like a fit in that regard since we require the rendering of multiple markup languages.
Has anyone done some benchmarking on JSF pages that they can share along with some straight JSP comparisons?
Thanks!
