SD card handle creation takes a long time with large folders

Hello Toradex Team,

I have a problem handling files on the SD card with a very large number of files within a folder.

Creating the handler in C # takes extremely long (15s). The writing of the file content is very fast <1s.

I also noticed that the RAM load during the handling process is very high.

TFAT brings no improvement. Even the choice of the SD card brings no difference.

I hope you can help me.

Best regards

Dear @Saphymo

To reproduce the issue, please let us know

  1. Which OS are you using.?
  2. What do you call a large number of files?

TFAT operations require more overhead compared to FAT, mainly while writing. Therefore I expect the TFAT performance to be worse than the FAT performance.
