 With 10 x 6 = 60 SOS filters, the component uses about 60-70% of the CPU, and I assume the web server also consumes some CPU power to send approximately 100 messages per second. So, this is quite a CPU-intensive task. I chose 6th-order filters somewhat arbitrarily; you could experiment with lower-order filters, which might meet your needs while using less CPU power.

 While this example serves as a stress test, you could also use it to monitor different frequencies over longer time intervals with less frequent updates.
