Slow in a sense that some extended time is observed as compared to the default. I already tested emphasizing the boot_delay=1 but to no avail. The reason why I removed it is because I want to change the settings of the HDMI display resolution as changes will not take effect with the [pi4] line in RPi 3B.

I don't think I'd ever tried tampering with config.txt after my
initial setup, but I found there was something weird with the default
MMC stack and it wouldn't tune sdhci frequency on any of my Pi3/Pi4.
GENERIC-MMCCAM performed wonderfully for me.
