Re: Why qt execution is so slow,this is a test
You want to enhance the performance of appending 1000000 characters to a string ? Simple answer would be - don't do it this way. Use QString::reserve to preallocate the string buffer and then insert characters into given position, this should work faster.

...or use QByteArray which shouldn't have all the UTF-8 overhead.

Reading the docs was helpful? No way! They are just there to look pretty.
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
