Is there any way to estimate the time it takes for an ISR() interrupt routine on an external interrupt pin to begin execution? The interrupt calls this function: void LED_V3::StartTimer() { TCCR1A = 0; // reset timer 1 TCCR1B = 0; // set up Timer 1 TCNT1 = 0; // reset count…

so consisten latency is kind of important.

On a web server? I hardly think so.
