    I'm interested in knowing the reasons why Safari, Chrome and Firefox have different memory utilisation and battery consumption rates. Each of these browsers uses a different rendering engine (Google's Chrome has forked Webkit to create Blink).

    The difference is quite noticeable on laptops running on sole battery power. You can perform a quick test by loading your favorite sites in about 5-10 tabs on each of these browsers and then tracking memory utilisation and battery consumption as well.

    Is anyone on CE aware of the technical reasons why these browsers consume resources differently?

    I have experienced a lot of this in my laptop. Opening a lot of tabs in Chrome created to much load on the RAM, That the system crashed too often. I guess Chrome ships all the plugins it needs inside it and when each tab is opened the plugins gets allocated for each and every tab individually resulting in too much load

    One reason which causes this difference, is the way in which these browsers handle their tabs and plugins, for example:
    Chrome creates a different process for each new tab whereas Firefox uses threads to handle this task.
    So chrome requires more memory as compared to Firefox for higher no of tabs, but it makes Chrome less vulnerable to crashes etc.
    Hope it helps!

    I would like to ask couple of questions here :
    1) Why Chromium creates large amount of cache compared to Firefox ?
    I use Firefox more than Chromium & still it has no cache, while Chromium have 400MB of cache.

    2) Where is this cache is located ? I tried searching, couldn't find it. Any idea ?
