Re: [infinispan-dev] File cache store comparison tests

Fyi - Input from Hiram on #jdg regarding levelDB configuration for better performance [1] chirino 2:48 was reviewing the leveldb bits and it seems like compression is off by default. Can anyone comment? dmehra 3:29 chirino: which leveldb bits are you referring to? chirino 3:30 https://github.com/infinispan/infinispan/blob/master/cachestore/leveldb/s... dmehra 3:31 chirino: what is the impact? and what should the value be? chirino 3:32 set it to CompressionType.SNAPPY 3:32 you get better perf. chirino 3:45 yeah if you guys are doing perf comparisons you really need to run /w SNAPPY enabled. 3:46 it can be a totally different beast. dmehra 3:46 chirino: how much expected speedup? chirino 3:46 depends on the data, but if the data compresses well, it can be HUGE. 3:47 there are JNI snappy libs too.. use that if you can as those too are faster. just add the following jars to your classpath: 3:49 https://gist.github.com/chirino/5879733 3:49 that way you can get JNI speed if it's available and fallback to pure java snappy if it's not.
