IMO, Good to add one perf test suite for the operations like other
library calls. It may be compared with TLS on same operation.
So that end users can decide to use the scheme based on their use
case, and we get performance test case to avoid future regression
for this library.
It may not show any difference in numbers, but once we have self
monitoring performance counters[1] it can in the future.
