Why is Opera so slow at loading pages

  • Opera seems to load pages extremely slow - over a minute for most pages. Safari on the other hand usually loads those same webpages in a few seconds.

  • It sounds like something is very wrong :).

    Check these:

    • Have you turned on Opera Turbo (Opera -> Opera Turbo)? If so turn it off
    • Do you have any additional security software running - third party firewalls, or even (gasp) a firewall?
    • Try running with a 'clean profile', you do this by renaming /Users/{YOURUSERNAME}/Library/Application Support/com.operasoftware.Opera while Opera isn't running
  • Thanks!
    I turned turbo off and matters improved, I'm not using any firewall.
    I could not find com.operasoftware.Opera in that folder but when I restarted my speed dial settings were reset to their original settings, I changed them to my preferences and speed has improved considerably.

  • Great to hear @cpatplan. Opera Turbo is a feature for when you're on a slow connection; it makes pages go via Opera's servers, where they are compressed, and then sent to you. When you're on a broadband connection it just slows things down.

    1. Open a new TAB/WINDOW. Type in opera:config
    2. Find the Performance dropdown box, near the bottom. Click it to have it display a bunch of new options.
    3. Make sure the settings are as follows for standard performance:
      Enable Pipeline - Checked
      HTTP Error Strategy - 2
      Max Connections Server - 16
      Max Connections Total - 64
      Network Buffer Size - 32
      No Connection Keepalive - Unchecked
      Non-Compliant Server 100 Continue - Unchecked
      Reduce Max Persistent HTTP Connections - Unchecked
      Synchronous DNS Lookup - Unchecked
    4. Hit save. Restart browser.

  • For http page, it's as fast as other browser. But when loading https page, Opera takes much longer, Yahoo Mail is a good example.

  • @ mathewandrson:
    opera:config does'nt work like you mentioned with Opera 33. By typing it, you will end at the "normal" configuration window!

  • Sorry to grave dig but has anyone found a solution?
