<![CDATA[Multiple Processes for opera.exe]]>Hi,

I recently upgraded to Opera 20 from Opera 12. When I start Opera (with speed dial) six processes of "opera.exe" appear in the task manager. Is this normal ?

Thanks.

it would probably already help if not each and every tab gets its process but rather just for each site.

Add --process-per-site option to Opera (launcher) command line. Check that updates do not reset this command line.

if idiots

Speaking of idiots...

compile stable x64 build

That will have zero effect on RAM usage. Switching to 64-bit builds just means each process of Opera would be able to access more RAM. Currently, each process can access a little under 4 GB of RAM. Switching to 64-bit build just means each process would then be able to access up to 16 TB of RAM. That tab would still use 300 MB.

well it pulls quite a lot of RAM (my GMail tab ALONE has 300 MB)

"They do not require any additional disk space compared to single-process programs"
True but they eat ram for breakfast

it would probably already help if not each and every tab gets its process but rather just for each site.

and try getting rid of a forkbomb. (someone actually linked me one. it wasnt a problem because I used firefox and I had only to shoot down one single process, and then unselect all the forkbombs in the sessionrestore "site" from firefox. with opera or chrome you wont be able to kill a forkbomb that easily

multiple processors as they use too much Disk space to run.

You do not have a proper understanding of how multi-process applications work. They do not require any additional disk space compared to single-process programs. That fact that Chrome also has issues and ever Firefox is experiencing problems tells me there is something wrong with your computer. Age is not a factor in whether a computer can malfunction or not. It does not matter of your computer is 4 months old or 4 years old, if you have damaged system files or malware or something like that it will start acting poorly regardless.

One little question about it though, the bar to the left of each process, when it's two or three lines tall, does that mean a single process is managing more than one tab?

I guess so but I'm not sure.

With it just sitting there doing nothing, one of the processes ranges from 10 to 15% of cpu time. Is there a way to determine which of my tabs that process belongs to?

You can check in Opera's task manager.

And, if it did, it was very rare, and it didn't bother me at all really. I also was never hacked through the browswer. So, all this undo attention to crash-proof security nonsense is just a flimsy excuse for writing bloatware. There was a time when developers wanted to run their software mean, and lean, but nowadays, they just borrow junk chromium bloat code, and take away all the staple features (like confirm on exit). what happened to you opera?

The browser, its GUI, each of its extensions, and each browser tab all run in their own separate processes. This is supposed to improve crash resistance and security should something in one of the processes go sour or rogue. All the chromish browsers use multi-process mechanisms (Chrome, Opera, Vivaldi, etc, etc) and the story is that Firefox will be moving to some sort of multiple-process system of its own shortly. At the end of the day, the technique does end up requiring a bit more RAM and processor cycles, but I'll leave the quality/magnitude of the crash/security improvements for others to debate.

How much RAM does your system have? 4 gigabytes is considered a pretty minimal amount to have if you want to run any version of Windows made after XP. As long as your system isn't using its swap file it doesn't matter how much load your RAM is under. That is what it is there for and you wont see performance fall if its under 90% load as long as the swap file isn't being used.

The point is that with a couple of open tabs displaying static content, Opera eats half a gig.

There is no reason to have multiple processes.

Sure there is. If a tab crashes and your whole web browser uses only a single process, welp, back to the desktop you go. If each tab and extension is in its own process, when one crashes it only takes out that one extension or tab. The browser keep on going and you can easily track down whats causing the problem without losing whatever else was open at the time. It also allows you to use multiple CPU cores for your program without having to make complex and difficult to maintain multi-threaded code.

The real problem with all browsing these days seems to be JavaScript. it is a lethal disease that has crept into internet. A good browser needs to put a muzzlie on JS. Otherwise it will gobble up everything and give you nothing but an "experience" you'll not want to repeat.

No plugins extensions etc in opera, pure stock. No malware (have run Malwarebytes to make sure, also run avast constantly)
No Opera turbo.

I frequently run the Opera as single app and it's the same as together with some 3d games. Tried without uTorrent -the same.
I guess I'm gonna reinstall 26 /rollback to v25 to see if it makes any difference.

I had a certain conflict in my Chrome recently, so...

Actually, it was a player, a separate app but sorta "integrated" etc.
Try running your browser for a while with everything else shut the hell down...:idea:

Although I don't experience any slowdowns in other programs (like 3d games). Google chrome is blazing fast.

BTW while I type this text I feel freezes like each 5 seconds (in text editor). Opened this same page in google chrome and editor shows no lags. Not whining, using opera since 2002 sun solaris version 🙂

Sounds to me like you have some kind of malware infection. Get a copy of Malwarebytes, Spybot and CCleaner and have them have a go at your system. Things like Norton are kind of useless for that.
