 Operations are on NodeInfo object. Benchmark tool, DPM, NCM and NMM run on the same physical machine in the lab. Ignite is run on two different physical machines in the lab (partitioned).

-For Insert operation, MAX represents total time to insert 1M entires into the cache and AVG represents the average time to insert one single entry. All other statistcs for Insert are not relevant and are shown as zero.
+Total time is applicable only to insert operations therefore query execution
