Hi All, Here it's a sample scala application,
https://gist.github.com/PingHao/0369a6d14c1de7072de57041a3fec0f7 I had compiled it with both Ignite 2.7.5 and 2.9.1 libraries, and got result by run on a 3 server nodes + 1 client node cluster. all nodes have 56 cpu cores and 100G+ free memory. same nodes, same client code, same Java 11 env, but performance result show 2.9.1 is much slower. Thread number set to 40, and batch size 2000. Ignite 2.7.5: putAllEntries rate > 2M / sec , latency avg 13 ms, latency is measure time cost on putAll() call Ignite 2.9.1: putAllEntries rate ~ 0.4M / sec, latency avg 120 ms Note that cache key, value is <Int, String> , all strings are size 10. I did ran yardstick test case, it didn't give so much difference. so here wander what's going on? Cheers Ping
