boost-base64-benchmark's Introduction

C++ Vector serialization benchmark

Boost version 1.62.0. Compiled with gcc/g++ 6.3.0 with -O3 optimizations.

Executed on an Intel T2310 CPU @1.45GHz.

boost::archive performances

Performances of boost's binary_archive, text_archive, xml_archive.

1M random elements, in full type range for integral types, between -1 and 1 for floating point types.

The base64.c and base64.h files are part of coreutils and are licensed under the GPLv2 license.

They have been modified to:

remove the include of the config.h file, which is specific to coreutils.
disable C++ mangling when used in a C++ project.
selectively inhibit the restrict keyword, which is not supported by C++ compilers.

The rest of the project is released under the MIT license.
