Opera 29 slow on Mac?

  • Nope, can't find dem anywhere.
    Looked in /System/Library/LaunchDaemons and everywhere, nothing.

    Finder Search (with hidden files) turned up nothing, too.

  • I have a similar issue with Opera 29 that didn't exist in Opera 28. There is nothing in the console messages and I do not have mDNS running, only discoveryd even though this Mac was upgraded from 10..9 to 10.10 and is currently running a beta of 10.10.4, but I had this issue under 10.10.3 public release as well. It is a late 2013 15" MacBook Pro Retina with 16GB of RAM, 1TB SSD, quad core 2.6GHz i7 and Nvidia GeForce GT 750M with 2GB of RAM. I couldn't use QuickTime to make a video as it would not display the spinning color wheel in the video, so it had to be recorded externally. The CPU was 80% or higher for the idle process and the RAM was had around 6GB free and no swap was used.

    Here is a video of the spinning wheel:

  • lanbrown I have the same model Mac, I sometimes see slow downs (I did a separate bug report for a GPU process bug in O 29), I also upgraded from 10.9 to 10.10

    I looked in both preference folders for the mDNS .plist files and found none

    Do you have a lot of windows open for Opera? I some times see when a page says it is loaded but I don't see the content (it is all white no page content is shown at all) for another few minutes

  • Chas4,

    I might have around 25 to 30. I have another MacBook Pro that was one generation prior and I have 40 to 50 tabs and I do not see this issue. Both machines have the same upgrades performed on them.

  • Try closing a few windows

    Does the older generation Mac have a Nvidia GPU?

  • I might have around 25 to 30. I have another MacBook Pro that was one generation prior and I have 40 to 50 tabs and I do not see this issue. Both machines have the same upgrades performed on them.

    Note @chas4 said windows, not tabs, since the problem he's seeing is related to having many windows open at the same time. I do not expect you to have the same problem as him with 'just' many tabs open.

    For some of you here: there's a bug in the Apple Dock we're investigating which causes OS X to get very slow if there are any minimized Opera windows. We're trying to find a workaround for it, but in any case check if you have any minimized Opera windows that could have an effect on what you're seeing.

  • I do have a lot of windows minimized to the Dock (8 right now & no slow down, but sometimes it is slower with many more)

  • Yes me too I have some issues using Opera, is getting slow using my Mac sometime when I using http://es.shopify.com to configure my online store compare to Chrome.

  • I use Opera before Safari and Firefox (recomended by my supplier)
    BUT
    The Opera is e x t r e m e s l o w and it doesnt help to restart either Opera or the Mac, at the same time the Firefox and Safari operates as normal.
    How can I detect the problem?

  • @eybby have you tried renaming your session files. That worked for me in the short-term.

    Quit Opera and go to ~/Library/Application Support/com.operasoftware.Opera/ Rename the files session.db, session-db.journal, session.dbak Restart Opera and it will re-create those files.

  • So far the Opera 30 release has fixed my issue. I figured it would as I switched to Chrome because Opera was just unusable. Chrome was one release ahead of Opera.

  • Thanks @lanbrown, Opera 30 indeed improves session handling so I'm glad that turned out to be the problem/fix for some of you.
