Time Scaling Issue on Toph

As we know Toph supports many language but often you try to solve a problem on Toph with efficient approach only to find out it cannot be solved with a language because the language tends to runs a little slower than others.
I think Toph should use time scaling like for example Codeforces globally.
Note that for languages like Ruby, Perl and Python 2x or 3x scaling is not enough. It needs to be 5x. And it needs to be global default, not just on per problem basis.
Codeforces time scaling value for reference:
