Thank you for adding the microbenchmark. Please update this BenchmarkArithmetic 
table with result from your latest run.

I usually do following before running this microbenchmark to get consistent 
result:

sudo cpupower frequency-set --governor performance
echo "1" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo

Also, make sure the impala and microbenchmarking code is from RELEASE build.

./buildall.sh -skiptests -release
