MacBook Pro 8.2 is very slow since updating to Big Sur via OpenCore.

I upgraded my PC to 16GB of RAM and a 240GB SD card. I had the official High Sierra and the computer ran very smoothly, except I couldn't open pages in Safari or download apps, so I opted to install Open Legacy Big Sur.

I have already applied all the patches and some advice that I have read on the Internet but I still cannot use the PC because it is so slow.

If anyone knows what r could be, I would be grateful if you could help me.
