switching to PRIMARY_SYNC configuration, PUT benchmarks dropped to 35K ops/sec. I dont think its a memory issue, because heap is configured to 10GB and entries are stored off-heap with Non-Heap memory set to unlimited. The server has 28GB and plenty of available memory.
Follows are the JVM Options: -server -Xms10g -Xmx10g -XX:NewSize=512m -XX:SurvivorRatio=6 -XX:+AlwaysPreTouch -XX:+UseG1GC -XX:MaxGCPauseMillis=2000 -XX:GCTimeRatio=4 -XX:InitiatingHeapOccupancyPercent=30 -XX:G1HeapRegionSize=8M -XX:ConcGCThreads=8 -XX:G1HeapWastePercent=10 -XX:+UseTLAB -XX:+ScavengeBeforeFullGC -XX:+DisableExplicitGC OS is Windows It is noticed that CPU does not go above 10% on both servers in both GET and PUT tests. Any recommendations to tune things further? -SM -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Poor-GET-performance-tp8319p8329.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
