As shown in https://github.com/taichi-dev/taichi/pull/3910, replacing property with simple attributes can speedup python part of taichi a lot.
Lessons learned is that we should avoid using @property when applicable since it's expensive. So let's review the usage of @property in our python codebase and replace them as much as possible.
Here's a list of simple grep in our codebase showing filenames with @property:
λ ~/github/taichi master rg "@property" python -l
python/taichi/_testing.py
python/taichi/lang/snode.py
python/taichi/lang/mesh.py
python/taichi/lang/impl.py
python/taichi/ui/gui.py
python/taichi/lang/any_array.py
python/taichi/lang/field.py
python/taichi/lang/ast/checkers.py
python/taichi/lang/_ndarray.py
python/taichi/lang/struct.py
python/taichi/snode/fields_builder.py
python/taichi/ui/window.py
python/taichi/snode/snode_tree.py
python/taichi/lang/matrix.py
Removing these should in general help speed up the python part of taichi programs.
