Mozilla & Gecko clones "A lot of people complain about the Firefox 'memory leak(s)'. All versions of Firefox no doubt leak memory - it is a common problem with software this complicated. We look to fix the issues where we can. David Baron and others have done a huge amount of excellent work in this area. What I think many people are talking about however with Firefox 1.5 is not really a memory leak at all. It is in fact a feature."

Firefox slow? Not on my end.

While I won't argue that Firefox takes up a good bit of memory, I really don't get how people can call it slow. Firefox, IE, Mozilla, Safari, Camino, Epiphany, Konqueror, aside from the user interface and subtle differences in page rendering, they all feel about the same to me. In fact I just ran a few tests right now just to make sure I'm not crazy.

Start time to a blank page:
Firefox 1.5.0.1: 3 seconds
Camino 1.0: 2 seconds
Safari 1.3.2: 1 seconds
Opera 8.51: 3 seconds
IE 5.2: crashed
Mozilla 1.7.12: 10 seconds
Konqueror 3.1.4: 2 seconds

Time to load osnews.com:
Firefox: 3 seconds
Camino: 2 seconds
Safari: 5 seconds
Opera: 2 seconds
IE: N/A
Mozilla 2 seconds
Konqueror: 10 seconds

About the only things that stand out here are Mozilla's load time and Konqueror's page load time. Everything else happens so fast that my times probably aren't even accurate. But that just proves my point. Everything else runs equally fast.

Now granted I ran this all on a Mac so things may be slighty different elsewhere, but then again I'm no stranger to Linux, Solaris, Windows, etc, and I've never noticed things being much different on any of those systems.

That's just because you have a lot of RAM. I have on my laptop 128 Mo, what should I do, buy a new computer only to browse websites ?

Tristan Nitot explained all this stuff before on his blog (not a bug, a feature). The only thing I don't get is : why then Opera uses much less memory ?

I have 512 megs, which I certainly wouldn't call excessive these days. But sure, my results might be different with only 128 megs of ram.

128MB of RAM is a pathetic amount to have in any machine this day in age...

How did you test page load time? I think, that it has to be tested on local server, because you can't blame browser for net slowdowns.

Browser load test should be made at least 10 times. How did you test it?

But see, that's the thing. Nothing's really slow. And sure I could get all scientific about this and average out 100 start times and whatnot, but I really don't feel up to it. Feel free though.

What you need to also consider is other things besides for page load time:
- Switching between tabs. In Opera, this is instantaneous. Firefox there is a delay
- Typing a url in the address field. There is a slight lag on this in Firefox.

I'm sure there are a few other subtle things. But people notice these, and it gives off a huge perception of being slow. And well, those things ARE slow compared to some competitors. You may think it's stupid and minor, but if it's the kind of thing you do a lot and it lags, some people can't stand that (like me).

Yeah well, I don't really see it. Switching between tabs is pretty much instantaneous here on my end, no matter what the browser is. Maybe my system is just too speedy and has too much ram to make for a good test platform. I dunno.

My system is 2.2Ghz with 1gb of memory, so it's not at all slow. However, I do notice a very slight delay in switching tabs. It's probably half a second or under, but I notice these things, even if most people don't.

And for the type lagging in the address bar.. that's much more noticable.

These things shouldn't bug me, nor do they affect anything, but they do bug me, and mostly because the same product from a different vendor doesn't do it. There's something in the back of my mind that asks "Why can't they make these simple things faster? If they can't do the simple things, why should I trust the browser to be faster than the other browsers?"

It's kind of illogical, but eh.

Sorry, I just don't see that on my system. Firefox is just as fast as Opera. It would be interesting to see a study that checks how fast/slow various browsers are at various tasks for a variety of systems. Determine what makes the most difference in performance - CPU, RAM, harddrive, type of net connection, etc..

These things are slow, but Opera does not properly queue them. That is, click several links in a row in FF to open new tabs. Itakes a few seconds, but all are opened. In Opera, one or two will be, then it gets busy, and I get the scroll cursor.

I think FF needs to work on its speed and RAM use, but it has many parts of the UI right that others do not, making for a more enjoyable experience.

P.S. I even managed to talk about Opera and FF and not invoke Fitts. I'm proud of myself ;-P.

It's irrelevant, because the issue here is memory leak. So the real problem arises when you open tons of tabs and then even after closing most of them your pc is still crawling, then you have to exit FF, or even kill it.

Perhaps you failed to notice the people complaining about Firefox performance at the beginning of this thread?
