Opera 21 on Win 7 Ultimate 64 bit

  • The new Opera version mentioned in the title slows down the complete PC. I use about 25 tabs - in the elder version without any problems - in the new version is no effective working possible. Has anyone a solution for this problem?

  • Generally, Opera 21 should be faster than Opera Presto. When Opera 17 was tested against the major browsers, it was noted that if you keep the browser open a lot, Opera Blink is the best choice because "initial page loads are the quickest of all the browsers tested."

    However, something that might relate to your issue. I did notice this comment today in an Opera interview (late 2013) about the changeover to Opera Blink, as it related to, among other things, Opera TV. "Some of our customers will stay on Opera Presto for a while because of their low-end devices, since Chromium/Blink is a more resource-hungry component . . .

    25 tabs is a lot. I don't know what the RAM situation is on your computer, or your Operating system, computer resources, etc. I did have one thought. With the extension, TooManyTabs for Chrome,

    you can move a portion of your tabs into a suspended category where they eat up no computer resources. It's easy to move them from suspended to active and back to suspended again. It seems like it might be useful to you. You can see if it makes a difference. (To use a Chrome extension in Opera, you need the Opera extension, "Download Chrome Extension. https://addons.opera.com/en/extensions/details/download-chrome-extension-9/?display=en)

  • It's known that Opera 21 is using a little bit more of RAM than 20.

    Have you tweaked any opera:flags? You should consider resetting them to default and observe the RAM usage.

    Disable plug-ins you don't use in opera:plugins.

    And instead of following @lem729's suggestion of installing the extension you may want to try an automated solution Opera Software is developing called "tab hibernation". You can enabled it in opera:flags and read more about its technical details and other options here.
