On Linux, accept4() does the same as accept() except that it allows the caller to specify some flags to set on the resulting socket. We use this to set the O_NONBLOCK flag and thus to save one fcntl() call in each connection. The effect is a small performance gain of around 1%. The option is automatically enabled when target linux2628 is set, or when the USE_ACCEPT4 Makefile variable is set. If the libc is too old to provide the equivalent function, this is automatically detected and our own function is used instead. In any case it is possible to force the use of our implementation with USE_MY_ACCEPT4. |
