Following are average execution time for running 14 queries against 16
million entries (DB size: 370 MB)

OFF HEAP memory mode - 47 millisec
ON HEAP memory mode - 16 millisec

why there is difference in execution times between off heap and on heap
memory modes as both are In-memory? What performance tuning can be applied
on off heap memory mode for better results?(I have also tried JVM tuning
mentioned in Ignite documentation, but its not giving any better results)
