Re: How should I debug or adobt better data processing for high sp

Hello Scott,
Thanks a lot for reply!
I thought if I use message for informing consumer thread that there is a
new
block of data it will cause a large amount of messages (more than 100/Sec)
only to perform synchronization. another problem with this approach is
that
producer thread has to have two separate buffers. because data stream
comes
constantly it has to be saved in a private buffer and then blocks of data
to
be transferred to the shared buffer. so this copy and pasting of data may
also exacerbate the situation. Of course I have no idea how bad situation
is
when one uses critical section but I presumed it is both safe and
ultimately
fast but you cast doubt over my presumption.

I was reluctant to use
messages even to inform CView that it has to redraw because new
information
has arrived so for each 10 block of data I send one message to CView for
update and it is not good because there are situations that only one block
of
date arrives and there will be no more data block to follow and CView will
have no idea that it has to update itself. All of this because I presumed
message puts heavy computational load on windows.
