$ sudo apt-get install linux-tools-common linux-tools-4.4.0-31-generic linux-cloud-tools-4.4.0-31-generic

To measure branch miss:

$ perf stat -e branch-misses <command>

To measure cache miss:

$ perf stat -e cache-misses <command>

To collect TLB miss:

$ perf stat -e dTLB-load-misses,iTLB-load-misses <command>

$ perf stat -e branch-misses ls>/dev/null

$ perf stat -e cache-misses ls>/dev/null

$ perf stat -e dTLB-load-misses,iTLB-load-misses ls>/dev/null
