It does feel fast at the starting, then after I open some 4 or 5 tabs in firefox it starts to slow down. ZorinOS 15.3 core was actually a bit better in terms of performance for me. Here are my laptop specs:
Processor: Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz
I've got 2 GPU's: AMD® Hainan / Mesa Intel® UHD Graphics 620 (KBL GT2)
Also, I haven't installed it yet, I'm just trying it through my USB. Will I experience a better performance improvement if I install it?
