Thank you very much for your response.
I tested as you said.

A script is like;
init
reset halt
sleep 10
poll
sleep 10
stm32x mass_erase 0
sleep 10
reset halt
sleep 10
flash write_image flash.elf 0 elf
sleep 10
target_request debugmsgs enable
trace point 1
reset halt
resume
sleep 10000

Result is below.

What you expect happened. From line 6, it is after 10 second from launched, the speed of message decreased.

What does symptom mean? I would like to under stand the situation or difficulty what I wanted.

I recall having looked at this ages ago. It's not as simple as increasing
the poll speed as other things need to happen in the system as well.

Does the performance improve while "sleep 10000" (sleep for 10 seconds)
run?
