In the meantime I created a small user interface with a rotating push button encoder and OLED display "Feather OLED 128x32" to config 4 channels with 4 pulses. But this needs still some debugging, the code is not so tidy.
The delay is still there but I did improve the jitter by using the correct ...

ESP32 Thing SparkFun RMT Pulse Generator 4 Channels Jitter 100ns
Hello
I'm programming with the Arduino IDE and hardware "ESP32 Thing with set to 80Mhz" from SparkFun.
My target application is a Pulse Generator for 4 Channels with low (no) Jitter.
See the following example code:
