Re: Search benchmark: 2.0 vs. 2.2-dev and heap sizing

This is interesting. Very large heaps can sometimes cause an expensive gc cycle ("Can heap be too big?" - http://www.javaperformancetuning.com/news/qotm045.shtml) and different memory allocation patterns between 2.0 and 2.2 could I think play in too, so it would be interesting to know the numbers

Search benchmark: 2.0 vs. 2.2-dev and heap sizing

Hi, I'm doing some Lucene search benchmarking (got to love massive query logs :)) and have 2 questions: 1) Has anyone compared Lucene 2.0 and 2.2-dev? My benchmarks found 2.2-dev (freshly baked) to be somewhat slower than 2.0, despite all those performance improvements (see CHANGES.txt)... Ha
