vert.x - Putting 2 millions objects in Hazelcast cluster of 5 nodes - what optimization we should do -

we have 2 millions objects coming rest api in chunks of 500 objects in each api call (apprx 750 mb of data in total). when put these objects in hazelcast cache following takes around 10 minutes – cpu 5-6% - makes sense because there 2 million blocking n/w calls. vertx.executeblocking { for(2 million times) { hazelcast.put(mapname, key, value) } } when don’t use vertx’s “executeblocking” , rather following whole process finish in 10-15 seconds cpu reaches 80% . using hazelcast mancenter, see 2 millions objects reflected in cache within 10-15 seconds. for(2 million times) { hazelcast.putasync(mapname, key, value) } when used #putall following cpu reaches 60% , better second approach . approach finishes in apprx 10 seconds. for(2 million objects in chunks of 500) { hazelcast.putall(mapname, collection-of-500-objects) } any optimization guys recommend? wonder why hazelcast spiking cpu much. fyi - think vertx.executeblocking executing piece of
