It so happened that I had to transfer to a slow car (1.4 GHz, 512 MB) while my laptop was under repair. By this time, I had already completely managed to transfer to Google Chrome - I was attracted by the speed of its work.
To my disappointment, it turned out to be not so smart in relation to its own services, for example, I have been terribly slowed down by Gmail, Google Docs, in particular Google tables (especially large ones).
And having started the same services in Firefox on my slow car, I was surprised to find that they just fly compared to chrome. At least when working in Gmail and Google’s large tiblice, there are no jerks when scrolling the page - a subjective assessment, but I hope gives an idea. In any case, when scrolling the page in chrome, the Windows task manager shows the processor load 100%, and if you do the same in FF, then no more than half.
Later I checked it on Google Chrome 3.0.190.4 - the same story ... try it yourself ...
