No, it's just a performance test of the browser, which is directly relative to the hardware it's used on... But the interesting thing you can do is install and test browsers on the same pc / laptop and that should give you a clear idea which browser works well on your hardware...
That is also my view on what is arguably best in that regard, because it is what worked best for your system specs should be the yardstick to measure this relative browser performance. Despite saying that modern browsers should have features which are very effective in carrying out routine works. Any of them should have the minimum built-in features instead of relying on third-party extensions.
I have 384 tabs open in chrome, maybe i work with 7-8 tabs, but every time i restart chrome, as usual i have my tabs there for me. point being, i really hate chrome, but it works best for my particular work, also there is a delay of 15secs in windows 10 compared to my stripped windows 7(i.e; as much of possible services are turned off or removed, only drivers i use are kept, as much of windows can be cut down has been cut, the orig source of the iso has also been removed by DMCA everywhere. its not for everyone but works for me)
That points out you don't really need to like a browser to prove its performance. Your case is a testament to that. We are sometime biased to other browsers which fall out of favour with our views. They might be subjected to our complacency with consistent use of particular ones or propagands we have read online, etc. Sometime it can be that we are not satisfied with the origin. Whatever reason that makes us to judge a browser on those ideas often doesn't say the truth about the capabilities including the performance we are discussing about here without testing it on our systems. However, benchmarks are great they don't often address all the reasons for the performance.
You mentioned Epic browser... It looks like an incredible browser with lots of features... But it's a huge security risk if you ask me...
On privacy Epic Browser is good with its built-in VPN, ad-block, control of what cookies are allowed, etc. I don't see how those stand for huge vulnerabilities compared to Vivaldi in early part of the discussion. It is a lightweight browser the developers so much concentrate attention on security. Why do you think it is a big security risk? Slimjet is using part of my CPU resources to compensate for its performance. It is indeed very fast for a lightweight browser.
The point is that the times when Opera was 10 time faster than everything else and (20 times faster than IE) are long gone. Nowadays all the three surviving engines are fast enough and the differences are practically negligible. The battle is about the features, the privacy and the protection against malware Opera still shines on 70% of the web, given it's incredibly light and efficient Presto engine, but given the lack of functional updates, it's slower than other browsers on many "internet 2.0" websites, starting from the most common one, facebook.com
You can spell it out here for me. The Epic Browser doesn't rely on the VPN though. Indeed, to be clear, it uses an encrypted proxy. Not that I am using it for my daily works. I only mentioned it to prove a point.
That's even more valid for VPNs. Actually they could made the like of spies easier . A vpn can be meaningful for a person living in a country where the government is known to spy its citizens, trough a vpn the user can bypass any control on his country, But for an user living in a supposedly free country a vpn means just concentrating all the traffic to one single point, if that point is controlled by a big brother or a government, your vpn becomes not just useless, it helps a lot who wants to collect your data.
For obvious reasons I use Vivaldi, before I was using Opera but when it was sold to the Chinese it was time to jump ship. There have been made some comments about Vivaldi that are simply not true. Currently at version 1.3, the browser is definitely not "slow" it's actually pretty fast. I'm using it with Ghostery, Ublock Origin and WebBoost extensions and all work flawlessly without any bugs. Granted, there is still some functionality missing (dev tools, sync) but if you look at how far they have come in so little time, it is well worth the wait. For me Firefox was always more "hyped" and I found it slow and a memory hog. Not using Chrome because I don't agree with Google's business model (read data mining). For the same reason I've got Edge as a secondary browser. As for Otter browser, I really liked it but development is slow, maybe it will reach the point that it becomes usable but not yet there. Cheers.
