What do you mean by "slow"? How is it shown?
I have a SD card with a read/write speed of 90/45 MB/s, no friezes, all very smoothly
i think its an old SD card, it seemed slower to boot from SD than internal.

The previous problem was because of wrong device tree or reset switch not working or any other else? How about WiFi and Bluetooth, are they also working?
Thanks.
Using LAN cable, but WIFI signal shows up, not tested bluetooth yet
