Opera uses lots of memory and CPU

Hi everyone,

I tried to solve this issue by myself and by using this and other Opera-specific Forums, but did not find any clue.

When I start Opera, it takes around 25% CPU usage, which is okay, I think its logic because I have a quadcore processor and Opera only runs on one core.

So I start browsing (or if I wait and do nothing its the same) and Opera uses more and more RAM (I check this through the Task-Manager). CPU-Usage is at or near 25% all the time, but Opera is usable.

After a few minutes (Opera uses about 800-900MB of RAM at this time) the browsing gets slower until Opera is unusable: Slow scrolling, Website loads around 30 seconds etc...). System stays responsive.

What I tried already: Use Safari or IE instead of Opera (turned out not to be a real a solution to me), installed older versions of Opera, Beta of next Opera, installed on a USB-Drive (i.e. USB-Mode), changed Memory Usage in Options (I think this only affects browsing history)...

No more ideas, and I am really afraid of switching to Safari or IE.

Note: I experienced this problem ONLY on this specific machine, but it is a clean Win7 installation on a new Notebook.

Whats a bit different: I have to connect outside throug proxy, but this was never a problem for Opera and all other browsers with my old Laptop, samte Win7 image.

Please help!

Opera version?

PC specs?

Similar problem: AVG 2012 reports high memory usage and advises I shut Opera down and restart. Seems to improve matters until the next time. (Running Windows 7 with intel quad and 4Gb of memory so it's not the computer spec).

I also have had to uninstall Opera 11.5 recently on three separate computers as it just loads lines of code/numbers/symbols etc for itself and web pages (though Opera speed dial displays OK). Running version 10 is fine as is the beta version 12 (Opera Next).

As I said I tried several Opera versions as older releases of 11 and Alpha (Beta?) of 12, all the same issue, so I'm back at 11.51.

I think It is not an issue of my PC specs, there is enough memory, IE also gets 1GB (when Opera is still running), I have 4GB of RAM. I think it must be an issue with the memory Opera demands, maybe caused from some malfunction or overflow or something.

Hi folks,

same problem applies to me - unfortunately. I am using Opera 11.51 on Windows XP SP3 (PC is an elder DualCore with 2 GB RAM). Right after starting Opera, its process consumes nearly 100 MB RAM without having done anything so far. After browsing a while, the memory consumption is up to 600 MB RAM, and Opera becomes unusable, i even can not stop it normally, have to kill the process with task manager. Sometimes this even happens 5 minutes after starting opera with only 3 or 4 open tabs...

I already tried to change some settings that i thought could consume memory:

• disabled thumbnails in tabs
• emptied my speed dial page
• changed number of remembered addresses
• disabled option "remember content on visited pages"
• minimized caches (RAM/HDD), i even tried to turn them off
• checked DOM storage (only some kB contained)
• tried new (empty!) profile

Nothing helped. I really don't know why Opera needs so much memory, i can not find any option that could be responsible for it.

Edit: hope you do not mind i appended to this task? I was not sure if i should make a separate one for my problem, because it seems to me its an Opera problem familiar to yours...

My Opera uses currently 1.4 Gb memory oO

Thats way too much! I have lot of pages opened though... If it wasn't for tab grouping and speed dial i would change browser already...

Try disabled JavaScript, and do not enable it then Opera won't hogging ridiculous amount of memory overtime.
However, doing so will render all extension & website rely on JavaScript completely broken & unusable.

Of course, the best solution for now would be simply use other modern browser until Opera is fixed.

Seems to me the issue will not be fixed soon as it is still present in the current alpha/beta.

Nevertheless I will try, but JavaScript is still widely spread so it seems not to be a good thing to turn it off.

As korda-machala said 1,4 GB is too much, thats not my problem though, I have enough RAM to let Opera use it, but around 800-900 MB it gets unusable. It could grab more memory, there is enough left, I don't know why its getting unstable/stocking here.

EDIT: Seems not to work for me. Only 700 MB RAM but still 25% CPU and unusable. I wonder why this is the only machine with problems, I have installed Opera on around 6-8 Systems, all work great but this one. Nothing special, nothing changed. Normal Win7, normal Hardware...

Disabling JavaScript did not make a difference for me too.

At home, i did not have such Problems yet; so i also had a look at the differences between my PC at work and my laptop at home; my PC at work uses XP SP3 and connects through a Proxy (squid), my Laptop at home has Windows 7 and a direct connection (through router) to the internet.

What has helped a little bit - because it stopped Opera from freezing - was disabling Pipelining:
opera:config#Performance

But that made Opera quite slow... so this is not an optimal "workaround" at all.

I'm also having RAM and CPU hogging issues with Opera. In my case, it's 11.52 running under XP Pro on a 32-bit 3GHz dual-core Pentium w/ 2GB RAM and several GB of free space on my drive.

I have six pinned tabs; two tab groups (one with three tabs and one with four tabs); plus three additional tabs all on the tab bar. After being open for 30 minutes, here are the stats for the Opera process:

CPU Average: 48.54% (usage has spiked to 56% while idling)
Threads: 15
Handles: 550
Memory (Private Bytes): 795,000+ K
Page Faults: 2,650,000+ (and growing very fast)

Every 15 seconds or so, Opera grabs so much of my CPU that my system freezes for about seven seconds. 11.52, as it stands right now, is unusable for me.

Checked for viruses? There could viruses in your Opera cache including Java. Try deleting all your cache, including Flash even. Opera has similar behavior when it's mass loading RSS feeds. Memory is fine, doesn't seem to be using much, even the CPU seems fine, nevertheless Opera gets a huge hit on responsiveness when in the process of loading RSS feeds. In your case, Opera seems to be expanding in HDD memory instead of RAM. HDD is much slower to run programs from than RAM. May be it's a memory leak, and Opera needs to address it.

Its a clean system (working place), similar that from uhecker (connecting through proxy) but Win7. On other machines I never encountered any problem like this.
Have you read the whole thread? Because I mentioned at the beginning that 25% seems not okay for me, because it's a 4 core machine, so Opera grabs the complete CPU power from one core -> as much as it can get. Memory also okay in the amount, but it starts at around 200-300 MB RAM and goes up and up.

All this while idle!

EDIT: There are no viruses and the Cache was empty most of the time as I installed multiple versions of Opera and also tried to install in a clean folder in USB mode.

Opera for my Windows XP Pro SP3 32bit plus all updates machine has also become unusable since updating from 11.51 to 11.52. I wouldn't be here whining about it, except for the fact that using the bug report wizard the last 24 hours has resulted in this other dead end...

Bug Description (that I wanted to report, but couldn't due to Bug Report Wizard failure).
What kind of bug is this?
Other problem

Where is the problem?
Not sure/Other

Brief summary of the problem encountered
100% CPU usage when sending a request for a page, even the Speed Dial page.

What URL triggers this bug, if any?
All, including Opera's home page, Fastmail homepage and Speed Dial page.

Describe in 3 steps or more how to reproduce this bug
1. Update to or reinstall latest Opera 11.52 build 1100 (from 11.51)
2. Request a page: doesn't matter if in a new tab or not.
3. See 100 percent CPU usage during this "request page" stage for several seconds, before page contents begin to display

1. What do you expect to happen?
Request sent near instantaneously with minimal CPU usage

What actually happens?
100 percent CPU usage for a several seconds, reducing to near zero when page starts to load.
Oh yes, and 100 percent CPU usage even when closing a tab.

Looks like I'll have to roll-back to 11.51 for now.

Cheerio.

Ok, it seems I can join the club.
My specs:

8gb ram
Opera 11:52 build 1100

Ram used by Opera always between 600mb and 760mb.
Lately the fan started to go crazy too and is not any laptop fault. When Opera is not running the fan work at normal speed.

I am using Opera 11.52 and have the same problem.

Just having looked, I also have near 480Мб of working set (physical memory) in my Opera 11.52 and Windows 7.
