A) Do not create or acquire repeatedly. Do it once before the loop starts and just insert new elements in the queue.
B) Similar to what I said for A. Destroy the task when you leave the loop.
C) Add a wait timer in all loops so they do not run too fast and goble up all of the CPU.
D) Send data two places. Your existing queue sends data to second loop which does logging only (in my revised scheme). Move all of your number crunching from loop two to the display loop at the bottom. Feed the bottom from a second queue you will be feeding as you are doing with your existing "data" queue in the top loop.This will eliminate three queues and prevent your number crunching from gettin the way of your data logging. The user interface should be the only loop that can be hurt number crunching and dispaly updates.
Have fun,
Ben
