the problem of slowing down the file that is opened append

[erkanakarcay]

I have opened the file such as the below, but a short time a later process of writing occur so slowing

SPIFFS_open(&fs, "my_file", SPIFFS_APPEND | SPIFFS_RDWR, 0);
SPIFFS_write(&fs, fd, (uint8_t *) &Data, sizeof (Data);
SPIFFS_close(&fs, fd);

thanks

I have analyzed the problem. I want to write 1KByte data but this process slows after the 12KByte data. At first 12Kbyte data, the writing process reads 3 flash areas and writes. However, after the 12Kbyte data, this process reads a lot of flash areas and writes.
