    Default Qt Threads vs Native Threads performance

    Hi there

    I have to develop a multithread application, and i want to use Qt since that application has to be used in Linux and FreeBSD. I have to implement a file server.
    Qt gives me a multiplataform solution.
    But what about performance ? Could be much less than using native threads ?

    Default Re: Qt Threads vs Native Threads performance

    Note: Qt's threading classes are implemented with native threading APIs; e.g., Win32 and pthreads.
    Quoted from here

    So with one level of abstraction over the native threads you should not "see" a difference in performance. (You can always test and see exactly how much performance you gain if you use native threads)
