our benchmark test, using the standard tag library in JSP page is 10 times 
slower than using the embedded <java> tag directly. I am not sure if anybody

We have not heard many general complaints, but ongoing performance 
investigations are being conducted; Peter Lin and others are investigating 
various performance issues and areas that present likely candidates for 
optimization.  I shall soon apply a patch, for instance, to cache parsed 
representations of XPath expressions.  If you suspect the problems are both (a) 
addressable and (b) apparent across all of JSTL, then profiling reports might 
help us determine where (and ultimately why) the implementation is slow on your
