That's correct. I have compared both scenarios without considering the first JSP access (I know how JSP works at this level). Thanks again for your time :) Cheers Jordi Rubio Moreno -----Mensaje original----- De: Jeromy Evans [mailto:[EMAIL PROTECTED] Enviado el: lunes, 28 de mayo de 2007 14:37 Para: Struts Users Mailing List Asunto: Re: [S2] Freemarker vs struts taglibs Jordi Rubio Moreno wrote: > Is JSP taglib too slow and not recommended solution for production portals? Hi Jordi, I'm impressed you made the effort to compare Freemarker vs Jsp performance. I've re-posted your question at the top of this email in the hope that it gains the attention of some of the more experienced developers. In your test did you ensure your comparison doesn't include the first time the JSP is retrieved? On the first request the JSP is converted to java and then compiled which is inevitably slow. Subsequent requests execute the bytecode and are much faster. Did you take this into account? Within struts2, I think it would be a fair assumption that JSP will always be somewhat slower than pure Freemaker because the UIBeans are rendering using the Freemarker template engine anyway. I wouldn't have imagined it would be <10% slower but have no evidence. I'll try to run the same comparison if I get a spare moment. Anyone else care to comment?
