Hi, I'm resurrecting this thread with some new findings. I re-ran many of the benchmarks we've been following, pitting Jackrabbit 2.8.0 against Oak 1.0.1 with TarMK. The results look pretty nice:
Summary (90%, lower is better) Benchmark Jackrabbit Oak-Tar -------------------------------------------------- ReadPropertyTest 45 4 SetPropertyTest 1179 119 SmallFileReadTest 47 7 SmallFileWriteTest 182 43 ConcurrentReadTest 1201 710 ConcurrentReadWriteTest 1900 775 ConcurrentWriteReadTest 1009 108 ConcurrentWriteTest 532 101 See https://gist.github.com/jukka/078bd524aa0ba36b184b for details. I also tried including MongoMK results, but the benchmark got stuck in ConcurrentReadTest. I'll re-try today and will file a bug if I can reproduce the problem. BR, Jukka Zitting
