Simple non-academic performance comparison of various operations on C++ strings:
C strings, character arrays, std::string and std::wstring classes
as well as some of the Boost string algorithms.
The benchmarks use Celero library.
The tests use Catch.

See charts generate with Bokeh.
Detailed results are displayed in tabular form in the Travis CI and AppVeyor build logs.
Build and run the benchmark with:
cmake -DCMAKE_BUILD_TYPE=Release /path/to/string_benchmark
make
cmake -G "Visual Studio 15 2017 Win64" -DBOOST_ROOT=C:/local/boost_1_63_0 /path/to/string_benchmark
msbuild /p:Configuration=Release /p:Platform=x64 string_benchmark.sln
CMake generates RUN target. It runs all benchmarks automatically after successful
build and tests run, saving results in CSV files named after benchmark programs.
Celero command line options are available.
benchmark_iends_with -t benchmark_iends_with.csv
benchmark_istarts_with -t benchmark_istarts_with.csv

This project is driven by curiosity and for my own purposes. This is not a rocket science, but a simple set of C++ programs, with likelyhood of bugs, incorrectness or inconsistencies. Found any, please report. Comments and improvements are always welcome!
