3)
UI responds to scrolls and clicks within 1 second at the latest.
4)
UI response is slow.
It takes 2-5 seconds to respond to scrolls and clicks.

There is no problem immediately after startup, but after a while the response slows down.
It takes about 30 seconds after startup to operate at normal response speed.
When I restart the application, the response is just as slow.
