Pair Firefox with a fast DNS, and it's noticably faster than Chrome, for the last 3 years or so.
I discovered it accidentally, after switching to local DNS at the office. We run one of the nation-wide ones in a pretty close proximity in network terms.
From my desk:
local one - 0.029 seconds
1.1.1.1 - 0.035 seconds
8.8.8.8 - 0.120 seconds
Normally it should be, but Firefox's behavior is very sensitive to DNS response speed. Sounds not intuitive, but I think they're not using glibc's caching, or doing something by themselves.All of the networks I have have a DNS server around that speed now, and Firefox works visibly faster on all of them. Possibly an intersection between human perception and hardware capabilities of my systems at hand.
