Hi, It's normal that writing to disk is causing the degradation. You can do several optimizations to speed up writting to disk:
https://apacheignite.readme.io/docs/durable-memory-tuning https://apacheignite.readme.io/docs/performance-tips However you can try to test your example with next DefaultDataRegion configuration: <property name="dataStorageConfiguration"> <bean class="org.apache.ignite.configuration.DataStorageConfiguration"> <property name="defaultDataRegionConfiguration"> <bean class="org.apache.ignite.configuration.DataRegionConfiguration"> <property name="name" value="Default_Region"/> <property name="maxSize" value="#{4L * 1024 * 1024 * 1024}"/> <property name="persistenceEnabled" value="true"/> <property name="checkpointPageBufferSize" value="#{1024L * 1024 * 1024}"/> </bean> </property> <property name="walMode" value="NONE"/> <property name="pageSize" value="#{4 * 1024}"/> <property name="writeThrottlingEnabled" value="true"/> </bean> </property> You can also set walMode to NONE but in this case you can lose the data. Also if you have more then one hard disk then you can think about separating of the data and wal: https://apacheignite.readme.io/docs/durable-memory-tuning#section-separate-disk-device-for-wal According your example. It looks like ok but I don't see where you close your streamer. BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
