[infinispan-dev] Performance based on contention

2013-01-04 Thread Radim Vansa
Hi, I have created a comparison how JDG (library mode) behaves depending on the contention on keys. The test runs standard (20% puts, 80% gets) stress test on different amount of keys (while there are always 80k keys loaded into the cache) with 10 concurrent threads on each of 8 nodes, for 10

Very interesting results, and thanks Mircea to implement the new pattern! The effect on near-CPU caches is an interesting hypothesis, it would be nice to measure it; if you happen to run them again, could you use perf ? Last time I had run it - almost a year ago - the counters had shown very
