APAR status Closed as program error. Error description Customer has > 100 custom tags on each JSP, and the compile time is taking too long. He believes that the problem is in the JSPRuntimeLibrary, and the fact that it gets called for every parameter of every tag.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server 4.0 using * * jsp's containing useBean or custom tags. * * Significant performance improvement * * when running multiple tags since the * * fix caches the tags instead of making * * introspection calls each time a tag * * is used. * **************************************************************** * PROBLEM DESCRIPTION: Performance problem when using custom * * tags or useBean tags. WebSphere was * * making introspection calls for each * * jsp tag it encountered. * **************************************************************** * RECOMMENDATION: * **************************************************************** Request for performance improvements involving jsp custom tags.Problem conclusion Created a caching object to keep track of which tags have been called and what type of propery is being used. This eliminates multiple introspection calls for the same tag thus improving performance.Temporary fix /wasdoc0/apars/pq51741/354/PQ51741.jarComments
