Firefox has surpassed Chrome on Speedometer

>>akyuu+(OP)
I've used Firefox as my primary browser since the "Quantum" in 2017. Chrome still feels snappier, but Firefox's Container Tabs is hard for me to imagine losing.

Chrome's most of the snappiness is coming from how it handles the DNS queries internally from my experience.

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.

>>bayind+i8
which is a fast DNS? 1.1.1.1 ? I thought the OS caches DNS anyway, so shouldn't matter much in day to day browsing.

>>EVa5I7+T8
Anything you can "time nslookup" in or under 0.03 seconds (in "real" 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.

>>bayind+c9
In the past, at least, firefox has done its own caching since expiring my OS dns cache was insufficient to get it to pick up a change in DNS.

>>aidenn+Ek
Good reason to avoid Firefox for development imo. Nothing is more annoying than mysterious cache interventions when you're trying to get a handle on an unrelated problem.

>>CmdrKr+fA
Dev tools automatically disables caching for that tab, by default.

CTRL+SHIFT+R always disables cache for that reload, too.

>>bayind+AQ
In the dev tools settings there is a checkbox "Disable HTTP Cache (when toolbox is open)" which name seems to imply that this only applies to the resources that make up the page, not to DNS lookups (about:config name is devtools.cache.disabled, and it defaults to false).

I investigated and found that Firefox's in-memory DNS cache can be manually cleared by clicking a button in about:networking. To be fair Chrome also has a similar cache and method for clearing it. See: https://www.makeuseof.com/chrome-edge-firefox-safari-opera-b...
