maximum input clock pulse any gpio on ESP32

[KamalS]

i'm trying to decode ws2811 signal

read each byte & store in sd card (during 50us reset pulse of ws2811 protocol)

Low Pulse = 0.4us High + 0.85us Low
High Pulse = 0.8us High + 0.45us Low
Reset = >50 us

24 bit for each led (RGB each 8bit = 24)
its Clock Pulse rate nearly 800Kbps

FF00FF (Green= all bit high,Red = 00 all bit low, Green = FF all bit high)


possible>> reading performance will get batter by disable all other stacks which will handled by processor?

all i want to know that what is maximum input signal interrupt count?

note:
no any other parallel process(1: sd card writing)
no wifi/bt ware used.

Suggest you use the RMT for this instead.
