Hello All.
I have a funny thing going on with pthreads in my Arm Linux application.
First, a little background. I'm using the "nanoEngine" from Brightstar
Engineering. Thus, I don't really know what kernel I'm running, but I can
find it out if anyone needs it to help out.
Anyway, I'm finding that I get a performance hit after a certain thread is
woken up by a condition variable and then killed. Now, this may not have
anything to do with the thread itself, I guess. The thread reads from a
serial port, placing data a byte at a time into a file.
After the thread is done it goes back to sleep, and my application
continues, however it is substantially slower (about 14% slower). I have
closed all files. Also, I have even tried killing the thread all together
(instead of putting it back to sleep) and this did not help either.
Has anyone heard of this?
Thanks,
Phil
