Hi, what I figured out with performance testing is the following: When you use default settings it doe snot run enough queries by default and instead repeats the whole JVM startup several times (i think 20 times). Because the optimizations of hotspot are quite slow and at beginning the code creates many object instances on heap so GC runs extensively, so you need to tune the settings a bit: - use huge dataset (wikimedium is ok, but needs more queries) - use many queries per run - reduce number of JVM startups (5 should be enough) Uwe -- This is an automated message from the Apache Git Service.
