Monotonic

A boost library propsal: Fastest C++ Allocator. See original boost documentation and original code with documentation here.

This library provides the fastest way to manage memory in a C++ application. Yes, that is a bold claim. See the exhaustive results.

There are no source files - to add Monotonic functionality to your project, simply get latest and add the root folder to your include path.

Building

Building Boost Requirements

First, build only the requirements:

From Command line

Windows

$ b2 address-model=64 link=static threading=multi runtime-link=shared build-dir=build\x86 install --prefix="c:\lib\boost\" filesystem chrono regex threading

Ubuntu

$ sudo apt-get intall libdev-boost-filesystem libdev-boost-chrono libdev-boost-regex

Then build the test and performance harnesses:

$ mkdir -p build && cd build && cmake .. && make

Testing

Tried and tested on Win7, Win8, Win10, Ubuntu and macOS.

Results

See all comparative results, going back to 2009, here.

These are the latest results as of April 2021.

All numbers are normalised by the time taken for Monotonic, so a number < 0 means faster, a number > 0 means slower by that factor.
