Why is fmincon slower in comparison to other solvers?

Hello everyone.
I was solving an optimization problem using fmincon and IPOPT. I found that fmincon takes more time to compute the optimal solution. Is it because fmincon is written in pure MATLAB over IPOPT that is written in C++ ?.

I reached to this topic while googling an opposit question, I was running a simple optimization and saw fmincon using interior-point algorithm is faster than IPOPT and was wondering why?

That might be one of the reasons, however you may try Nondefault option of Algorithm as ‘sqp’, which can be sometimes faster.
