I use gphoto2 --list-files to show the files in camera. It's cost 38.2s to list 766 files. Is it the reason of camera itself？

It is likely the camera itself taking so long.

gphoto2 -L --debug --debug-logfile=list-files.log

will generate a list-files.log with timestamps to check where it takes so much time
