The split between SymPy functions and Mathics wrappers around these functions, together with the pattern matching is probably responsible for the slower system.

The split between SymPy functions and Mathics wrappers around these functions, together with the pattern matching is probably responsible for the slower system. Therefore in the Symja project[0] we try to implement it all together in one (Java) library. Mathematica syntax can be tested in the MMA Console[1], but the documentation of the functions [2] is in the "normally used Symja syntax", which is much easier to use for the "common calculator user".
