A pool of Digester instances isn't a good idea. Digester instances aren't "reusable" as described in the documentation; see also the FAQ entry about reusing instances: http://wiki.apache.org/jakarta-commons/Digester/FAQ And unfortunately I don't know of any way to cache the set of rules generated from an xmlrules file. You can certainly read the xmlrules file into memory as a string, and wrap that in an InputSource so that the xmlrules parsing at least doesn't have to do file I/O. However beyond that I don't know of any performance optimisations available.
