The results you are getting look strange to me. I tried running your code and configuration on a cluster and for OFFHEAP_TIERED I got results similar to yours, for ONHEAP_TIERED I got results twice as fast as off-heap. I would recommend adding at least a 30-seconds warmup to your code to get more stable and reliable results.
As for the CPU load, I also noticed about 20% load on servers (using top command), however this looks reasonable to me - it means that only single core out of 24 is loaded to about 1/5 of it's capacity. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/CPU-high-load-on-ignite-v1-3-tp1156p1172.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
