User Comments:
pclement: I clicked on a named query text emParty.createNamedQuery("Party.findPersonByIdentifyingAuthority", Person.class), which should take me to the query definition. It did work, but took long.



Maximum slowness yet reported was 29633 ms, average is 29633

I'm not seeing anything spectacularly wrong with MavenFileEncodingQueryImpl, or FileEncodingQuery in general. It just appears to get called very often.

reassigning to javaee to evaluate the namedqueryhyperlinkprovider usage of lazylines api. other possible culprit might be the openide/text code itself.


pclement: please use a more recent version of jdk. I've seen a lot OS level IO slowness reports with jdks lower than update 21.
