0.90 1.1 benchmark http://jakarta.apache.org/taglibs/benchmark A tag library that facilitates performance testing of other tag libraries or JSP constructs. duration org.apache.taglibs.benchmark.Duration JSP Calculates and prints the number of milliseconds taken (in elapsed, "clock" time) to calculate its body. The number is printed after the body. As a hack, this tag can be enclosed by <datetime:format> with an appropriate formatting string (i.e., just referring to hours, minutes, and seconds) to print out a reasonably readable duration. repeat false false output false false exclude org.apache.taglibs.benchmark.Exclude JSP Excludes its body from the overall benchmarking test. Some small amount of time is necessary to process these tags themselves, so they are not completely transparent. Nonetheless, they may be useful for integrated timing of a subset of a compound computation.
