I have a question not Javascript related, i understand it probably should be done in assembler or machinecode, but i am just not up to it so i look for alternatives.

What programming language do have fast read write IO to file?
It need to be able to read write continous, but not synchronus("half duplex"?)

And there is no need for multiple threads read and write to same file, just a single thread at half duplex "finding position and inserting".

Could python, do this in an efficient manner? 
Or should i use C?

It is also a question about searching within the file at fastest speed possible.
