Subject System Parameters to improve CPU utilization
Date Fri, 09 Jun 2017 10:21:26 GMT
Hi, 
       For my ignite data caching process i have recorded following
statistics. In which I have found my CPU utilization is not much(only
60-70%). Also during this run high number of minor page faults, context
switches/sec are seen. Are these parameters limiting my system performance?
Are there any tuning that I can apply to improve CPU utilization?

*Page Faults :*

*Context Switches/sec :*

I have also tried increasing setStartCacheSize for cache but still same
number of Page faults, Context switches/sec and CPU utilization is seen.

*Page Faults when setCacheStartSize is set to 60*1024*1024(for 60M entries
in our case):*
