Mozilla complaining about Linux

The title is... Optimizing Firefox: Why Large Applications Start Slowly on Linux

The real question is why firefox is called a large application?.. All it does is display pictures and text :S

Although linux (and most unix) operating systems do not provide the user with a choice of installing older software. I doubt firefox v1 or v2 would start slowly.

This has been discussed before. It's large because it actually has more parts than one might think.

In my opinion that's a gross oversimplification.

How browsers work.
The browser's main components are:

The user interface - this includes the address bar, back/forward button, bookmarking menu etc. Every part of the browser display except the main window where you see the requested page.

The browser engine - marshalls the actions between the UI and the rendering engine.

The rendering engine - responsible for displaying the requested content. For example if the requested content is HTML, it is responsible for parsing the HTML and CSS and displaying the parsed content on the screen.

Networking - used for network calls, like HTTP requests. It has platform independent interface and underneath implementations for each platform.

UI backend - used for drawing basic widgets like combo boxes and windows. It exposes a generic interface that is not platform specific. Underneath it uses the operating system user interface methods.

JavaScript interpreter. Used to parse and execute the JavaScript code.

Data storage. This is a persistence layer. The browser needs to save all sorts of data on the hard disk, for examples, cookies. The new HTML specification (HTML5) defines 'web database' which is a complete (although light) database in the browser.

Is that a presentation? So BIG font ...


wtf, I can't zoom out....

What I get to see is a presentation-like formatted page in which I can zoom out - but then again I do not allow JS by default.

Would like to see that test redone with ZFS and a SSD-Cache...

Then what actually does it do?

Bomard you with flash ads, store and hide tracking cookies, ask for updates any random(100) seconds, install spyware, require GL for rendering, create new demand for increased file system space, ...

And what should browser do?
Click to expand...
Mostly nothing of the aforementioned ;)

Ok, seriously now: a browser does more than display text and graphics. It should do more, like manage my bookmarks.
There are more requirements to it than just "what do I need it to do?" but "what does it need to be useful for mostly anyone without getting in the way of almost anything".
Putting that into words is complicated, I would say.
 
Even so, chromium starts up significantly faster than firefox, and I don't think anyone can claim that it does significantly less than firefox?
 
You can't go by start up time to determine what a program does compared to another. Firefox 7 starts up a lot faster than FF5 but does more things. Firefox is far more customizable and programmable than Chrome but even that may not be the reason it starts up slower.

Hah. Looking back at my post, I did sound like a bit of a troll. Sorry.

Perhaps what I meant to say is:- What extra features does Firefox offer us nowerdays that can justify the ~500% increase in cpu / memory requirements from say Netscape or even IE6.

Surely Firefox is more at fault than the linux kernel (this time) since even IE6 in wine starts faster than a native instance of Firefox 5.

I strongly believe that Firefox should be rewritten. Especially if the future of computers is going to rely so much on a web browser.

I would say that Firefox is a prime example of feature creep but... there havn't even really been any new features. It is just slower with almost every new version :S

Yes, I can.
There's a ton of ways in which you can customize FF that are unavailable on Chromium.
And while it is dog slow, which I hate, my productivity on competing browsers is way lower.

Nice one. I would have said my konqueror can do all that but do it better, but there i forgot konqi can't do flash (on SuSE, never had flash instaled on FreeBSD).

Managing your bookmarks (including the management dialog), won't take much more then some dozen kB of x86 code if you refer to some rather sophisticated frameworks as firefox does.

A browser is more or less an interpreter, as that is 90% of it's complexity. Rendering text and images into some widget and drawing it and some UI or managing some tcp connections and caches is hardly an issue.

Web servers, like browsers, like often do not conform to the HTTP specification these days, but you want your transfers to be made and don't care whether the server is properly replying or not. Also CMS just like "web designers" often are providing faulty/invalid html, javascript, css, ... so the next step would be "correcting" the content/logic - if your browser doesn't properly display my AJAX page that doesn't have a single semicolon in any javascript code, I won't tell you that I'm a poor programmer but "your browser sucks" instead. So have fun at interpreting what the original author was intending when programming, and next step is actually compiling the whole blob and running it - obviously you need it to run fast and compile even faster.

I could be wrong/outdated, but isn't wine's mshtml actually mozilla's gecko?

It's not just Firefox. All browsers have far more features that those could only dream of. Faster javascript engines, better network and parallel operation, asynchronous communication to the server, local storage, direct bit map drawing, image manipulation/rotation/transformation, more image format support, built in video and audio, built in form data and drag/drop between apps, and on and on. So much that I no longer have the ability to keep up with it all. At one time, I did everything to create a web site. Nowadays, I have to farm some of it out cause I just lose track of how things work.

Wouldn't know but IE6 is a mediocre embarrassment compared to FF1.0.

It has been rewritten. Anyone with the current version, FF6, will testify to how well it starts up and runs and any statements about being a memory hog are a past memory. I'm on FF9, the nightly update. You'd be shocked.

What version are you running man?!! While a user may not notice 3/4 of what's new, as a developer, there's so much going on, I can't keep up (as I said earlier)!

better network and parallel operation
Click to expand...
HTTP 1.1 Specification Chapter 8, Section 1.4:
Code: 
A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy.

But it's not like anyone cares about such things any more these days. IIRC Firefox has never cared for it to begin with.
 
ALL current browsers open more than two by default. I remember a lot of talk about that in the past but don't remember the conclusion. Note that SHOULD NOT does not make it a requirement so using more than two is not failing the specification.

But that's not what I meant by parallel operation. I'm talking about the fetching of data that, in the past, would have tied the browser up in blocking.

I meant IE6 with a full install (IEs4Linux). Not the default IE6/gecko compatibility stuff.
Although most web developers do not hack in IE6 support these days... At least the thing starts up quickly lol.

Regarding the new features of Firefox. On comparison of v2 and v5. I honestly do not see any new features between them and yet v5 takes up more than 3x the amount of ram.

Perhaps I am just using it wrong ;)

Don't say most. A lot of us still have to. One of the biggest customers of one of my clients is a big financial institution still entrenched with software that only runs on IE6. We charge them a 50% hourly premium for any work we do to hack IE6. Next year, we will do the same for IE7.

We have not seen FF2 in years. You must be doing something wrong if you didn't see the UI changes alone going to FF3 and especially FF4. btw, FF6 is the current version and FF7 will be out soon. But don't go by the version numbers anymore. It'll drive you crazy.
