## Use c++ instead of Python

The interface between the languages python and c++ makes it necessary to perform operations for the sole purpose of compatibility

between the otherwise incompatible languages. Often this includes copies of vectors of integers (whenever dimensions are specified

or queried) and sometimes even deep copies of whole tensors (`.from_ndarray()` and `.to_ndarray()`). The only way to get rid of

this overhead is to write your appliation in c++ instead of python. Most instructions that `xerus` offers for python look very

similar in c++, so a transition might be simpler than you think. Simply check out the rest of the tutorials to compare the code

snippets.



## Compiling Xerus with High Optimizations

Per default the library already compiles with high optimization settings (corresponding basically to `-O3`) as there is rarely
