This will of course hurt mac and windows users the most just because the size of resource usage for those dwarfs linux and chromeos. On linux with 8 gigs of ram I still have memory to spare for Spectre, on a work machine for windows that might be a negative impact. With only 4 gigs of ram on a windows machine you would probably run for the insecure embrace of edge.
