Selecting a file from SD card using a menu option is extremely slow

[lavato]

When printing from SD, scrolling trough file list is extremely slow.
This has been an annoyance for a while so decided to raise it.

I also believe the Buzzer issue I raised in a separate issue can be reproduced here.

Any other menu area is quick and responsive.

I am using RAMPS1.4 with the Full Discounted LCD option.

How many files do you have in the directory?

[lavato]

If more than 3-4 files, it start being very slow.

...to paint a better picture.

• When I turn the encoder while on the file list section, the selector only updates the screen about 2-4 second later.
• When I click on a file to print, it reacts about 2 seconds later.

Did you play with

//
// SD CARD: SPI SPEED
//
// Uncomment ONE of the following items to use a slower SPI transfer
// speed. This is usually required if you're getting volume init errors.
//
//#define SPI_SPEED SPI_HALF_SPEED
//#define SPI_SPEED SPI_QUARTER_SPEED
//#define SPI_SPEED SPI_EIGHTH_SPEED

?

@MarlinFirmware/documentation-maintainers We should mention this potential event in our SD Card section. Which I guess means adding an SD Card Printing section…
