Pyston is a fork of CPython with additional optimizations for performance. It is targeted at large real-world applications such as web serving, delivering up to a 25% speedup with no development work required.
Run make bm_nbody to build all the code and run a Python benchmark.
First do
git submodule update --init pyston/llvm pyston/bolt/bolt pyston/bolt/llvm pyston/LuaJIT
Pyston has the following build dependencies:
sudo apt-get install ninja-build cmake clang libssl-dev libsqlite3-dev luajit python3.8 zlib1g-dev virtualenv libjemalloc-dev
Extra dependencies for running the test suite:
sudo apt-get install libwebp-dev libjpeg-dev python3-gdbm python3-tk python3.8-dev
Extra dependencies for producing Pyston debian packages and portable directory release:
sudo apt-get install dh-make dh-exec debhelper patchelf
Run
make
An initial build will take quite a long time due to having to build LLVM twice, and subsequent builds are faster but still slow due to extra profiling steps.
A symlink to the final binary will be created with the name pyston3
- adjust

debian/changelogentry - adjust

We use a script which builds automatically packages for all supported distributions via docker (will take several hours):
- make sure your repos do not contain unwanted changes because they will get used to build the packages
- execute
$ pyston/tools/make_release.sh - output debian packages are now in
release/<version>/. Inside this directory are also different "portable dir" releases made from the different distibution deb packages. Decide on which portable dir to use - the oldest version will run with most dists but will also bundle the oldes libs.
