High memory usage after boot

Hello, I installed Arch on think-pad laptop with 16G Ram, And i noticed laptop is very slow and freezing with just Firefox open and terminal I booted and I looked into system monitor to notice that all of memory are consumed and the swap, even when i reboot and just login and didn't open anything yet.

I did a search but i didn't find any solution yet, if anyone could help.

Thank you! for some reason looks like mysql container with no databases yet! was consumed 80% of RAM, I stop it and will try to found out why.
