PHP doesn't scale as well under heavy load. If they are genuinely interested in scalability, figures 4-12 of http://www.trl.ibm.com/people/mich/pub/200812_middleware2008specweb.pdf should be interesting to them. I'm also particularly amused by the topmost set of bars in figure 2, given how proud the perl-ites are of their RE library and performance ;-). I copy the paper's conclusions here: "8 Conclusion "When implementing a web server system which will never experience high load, or in which performance, throughput, and reliability under high load is not an issue, then the use of any of the analyzed languages or web servers will achieve similar performance results. If outstanding performance and throughput is the primary goal, then the use of JSP over PHP is advisable. However, if a 5-10% difference in throughput and performance is acceptable, then the implementer of a web system can achieve similar results using either PHP or JSP. In which case, other requirements such as developer language familiarity and programming efficiency, maintainability, security, reliability, middleware compatibility, etc. would be the deciding factors. It is also reassuring to developers of both language runtimes and web servers, that enhancements to either can offer performance improvements to the community." - Peter --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
