arne-bdt opened a new issue, #2740:
URL: https://github.com/apache/jena/issues/2740
### Version
5.2.0-SNAPSHOT
### Feature
Profiling shows that resolving IRIs takes a lot of time when parsing
RDF/XML.
(Parsers: RRX.RDFXML_SAX, RRX.RDFXML_StAX_ev, RRX.RDFXML_StAX_sr )
There were two main things, I could do about it:
- In all current RRX-parsers, many IRIs are parsed twice, when "private Node
iriResolve(String uriStr, ..." is called.
--> I added "public Node createURI(IRIx iriX, ...);" to the
ParserProfile, which simply uses the given IRI instead of resolving it again.
--> in some cases this made the reader 25% faster
- adding general IRIx caching
`(org.apache.jena.atlas.lib.cache.CacheSimple`) in the parsers where the
already cached org.apache.jena.riot.system.ParserProfileStd#resolver is not
applicable
--> in some cases this gave me another 10%
