Why are browsers so slow?

As a user of Opera browser in the good ol’ days, I share Ilya Birman’s pain

But I am not talking about rendering and scripts. I am talking about everything else. Safari may take a second or two just to open a new blank tab on a 2014 iMac. And with ten or fifteen open tabs it eventually becomes sluggish as hell. Chrome is better, but not much so.

… and this too …

What would you do today if you opened a link and saw a long article which you don’t have time to read right now, but want to read later? You would save a link and close the tab. But when your browser is fast, you just don’t tend to close tabs which you haven’t dealt with. In Opera, I would let tabs stay open for months without having any impact on my machine’s performance.

Wait, but didn’t I restart my computer or the browser sometimes? Of course I did. Unfortunately, modern browsers are so stupid that they reload all the tabs when you restart them. Which takes ages if you have a hundred of tabs. Opera was sane: it did not reload a tab unless you asked for it. It just reopened everything from cache. Which took a couple of seconds.

In fact, maybe it’s a good time to try out Opera browser again.  After all, the two primary reasons I’ve switched from it were:

So maybe it’s good enough in rendering department and I can have my performance and tab management back.  As Ilya mentions, no other browser came close to the tab management of Opera back in a day.  I frequently have a 30+ tabs open, and its only because that’s as much as Chrome can handle on my laptop.

Update: Tried out the latest version of Opera now for about half an hour.  I suddenly remembered another reason for why I’ve switched – fonts.  Default fonts configuration is far from optimal.  For multilingual pages (English and Russian) is more than horrific.  Oh well, I guess, I’ll have to wait some more.
