which is faster if we compares opera, mozilla, and firefox?
which is faster from your experience?

david_ross · 04-11-2004, 01:01 PM

Personally I would say Firefox but I use Mozilla because it has a mail client too.

firefox/firebox are the same as mozilla at their core, but they are also much lighter thus faster.

opera has a lot of extra features so its heavier on the OS. it takes longer to start up and will crash more often then the other 2 will, but it is the browser i choose to use just because i am very comfortable with it and like a lot of the extra features.

once it is up and running it browses just as fast as the other 2.

I'd say none is that significantly faster, I think it more depends on the web's transfer speed. I'd say opera has the fastest page rendering speed, but that can easily be tweaked on firefox. As for mozilla, I think that it, however, is the slowest because it is jampacked with features.

its not to day that there is any browser that is faster then another
opera is said to be fastes coz its rendering capability.
letsay theres a html file is 50kb
opera can render the file even the browser has downloaded 10kb and on the screen you';; see 20% of the page and if some images also being downloaded on to pc then it will also shows on the 20% page

most browser like ie and mozilla/firefox ext to download upto 100% of the page and then render it
that is why opera is said faster then others

do firefox also has this feature that render whatever it gets like the way opera renders?

sometime and most of the time we dont need to load the whole page just to read a upper part of the page.

Opera is the fasttest & even when it crashes you can still continue browsing from where you left it.

Somewhere there was this browser comparision a long while ago - & Opera came out fastest more or less & IE & Firefox were very similiar speeds.

You can set the glayout.initialpaint.delay parameter to 0, that means firefox will start rendering the page immediately, rather than waiting a few milliseconds

Opera is the fastest. I logs you off every 15 minutes out of this forum since it is updated.

I use Opera the most. If are after speed Galeon, Epiphany, and Dillo are the quickest.

zaoka · 12-24-2005, 04:50 PM

I use ONLY Opera for more than 3 years now. Also I use its email client, notes, chat etc...

I really dont know what you talking about when you say Opera crashing???
It heppend to me 1-2 times monthly and its less that any browser that I used in past. It can not open some sites that are made for IE but other than that its very nice software.

The speed diference is measured in miliseconds so I do not know why make decision because of that?
Also with Opera when you use Back-Forward it show pages instatnly while with SOME other browsers you have to wait until it load them again.

I really like it much more than Firefox, Mozilla.. I just lose less time with its additional features.

I think Opera has better performance than Firefox and Mozilla. It also does not use as much memory as the mozilla based browsers. Konqueror seems to be the gui browser with the best performace, especially the version shipping with KDE 3.5.

Hi, I've just installed Opera and it's eating like 60% of CPU, my PC gets very slow when using it, I have a P4 1.6Ghz with 512Mb RAM and everything runs fine until I start Opera. I have confirmed it with top:

Code:

top - 09:59:18 up 43 min,  5 users,  load average: 0.74, 0.85, 1.04
Tasks: 112 total,   6 running, 105 sleeping,   0 stopped,   1 zombie
Cpu(s): 88.1% us,  9.5% sy,  0.0% ni,  2.4% id,  0.0% wa,  0.0% hi,  0.0% si
Mem:    515812k total,   506852k used,     8960k free,    24096k buffers
Swap:  1048568k total,       76k used,  1048492k free,   244780k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 3792 alexis    24   0 47604  24m  23m R 56.1  4.9   0:18.87 opera
 3466 alexis    15   0  163m  94m  35m S 14.6 18.8   8:13.87 firefox-bin

Sometimes %CPU for Opera gets as high as 65% just by having it open with one web page.

I disabled plugins and the problem persisted.

Any ideas?

Look at the amount of memory it consumes compared to your firefox-bin though? I run opera and don't see this problem though. At most I saw was about 10% CPU usage right when it was launching to open.

alexisb · 01-13-2006, 12:43 AM

Hi, you are right, memory usage is less in Opera, I had not noticed that. I guess it's hard to say which one is better: less memory used or less CPU used, may depend on many factors.

However, I tested with another box, same software but better hardware: P4 HT 2.8Ghz and 1Gb RAM, Opera runs with no problem, from 2% to 14% CPU depending on what you are browsing.

Regards!
