Profiling qt app: pthread_spin_init calls



  • Hi,

    I'm using Qt 5.02 (MinGW) to make a little board game. In order to get it to run faster, I ran it through Very Sleepy, and according to the results these are the three most called functions:

    pthread_spin_init
    pthread_tls_init
    pthread_setspecific

    This is very surprising to me, because I don't use any threads. The only thing I can think of, is my use of QVector and QSharedPointer that might do some locking/unlocking.

    I tried the same code on my Linux box (same hardware) and there I see that the results are significantly faster.

    Can anyone clue me in, why pthread function calls are being made?

    Thanks!
