I just tried; at least for gnome-terminal it did not at all change the results, even if a 1MByte buffer was used in setvbuf(). I thoght this could be related to our use of fflush() in stderr logging. But even when removing the fflush() I could still see those 64..128ms stalls when running the test program via gnome-terminal. Not sure what's going on, but definitely we can stop looking at setvbuf() as a solution. -- - Harald Welte <[email protected]> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
