Re: [qi4j-dev] OpenRDF performance problem...

[Stanislav Muhametsin]

It's 05:40 AM and I think it's time to sleep. ;) One thing the  
profiler could tell me certainly: the notifyChanges() method in  
RdfIndexingService.RdfEntityIndexerMixin is taking most time (around  
60-80%) when performing this test. So, it's somewhere in OpenRDF...  
the question lies, where. :) I poked around some code but didn't find  
anything specific. Althought the removing seems pretty heavy operation  
- it starts transactions, iterates over a lot of stuff, etc... Dunno,  
maybe it is supposed to be like that, but currently it is slow as  
hell. And I even have a what is considered a proper computer, with SSD  
drive (proper, Intel one). So I don't think it should be HW-related  
either.
