+A tool for comparing tcrypt speed test logs.
+
+Please note that for such a comparison, stability depends
+on whether we allow frequency to float or pin the frequency.
+
+Both support tests for operations within one second and
+cycles of operation.
+For example, use it in the bash script below.
+
+```bash
+#!/bin/bash
+
+# log file prefix
+seq_num=0
+
+# When sec=0, it will perform cycle tests;
+# otherwise, it indicates the duration of a single test
+sec=0
+num_mb=8
+mode=211
+
+# base speed test
+lsmod | grep pcrypt && modprobe -r pcrypt
+dmesg -C
+modprobe tcrypt alg="pcrypt(rfc4106(gcm(aes)))" type=3
+modprobe tcrypt mode=${mode} sec=${sec} num_mb=${num_mb}
+dmesg > ${seq_num}_base_dmesg.log
+
+# new speed test
+lsmod | grep pcrypt && modprobe -r pcrypt
+dmesg -C
+modprobe tcrypt alg="pcrypt(rfc4106(gcm(aes)))" type=3
+modprobe tcrypt mode=${mode} sec=${sec} num_mb=${num_mb}
