[CLOSED] Write File in QtConcurrent Threaded

[Francknos]

Hi everybody,

I have some code which save data in file, and it works fine but blocking my GUI.

I put all treatment in a thread using QtConcurrent::run. It's done and work fine with ProgressDialog and I can stop thread with a button.

But there is a probleme ...
When I run my code without thread, the writing speed is ~10 Mo/s.
When I run my code with thread, the writing speed is no more than ~1,8Mo/s.

Someone have and idea to write at ~10Mo/s with my thread or it's impossible?
