Opera (15-26) gets very slow as Sessions.db gets large

Hmm. I don't even have a session.db file and I can't remember off the top of my head what its used for. Do you use 'Continue where I left off' under Startup Option in Settings? I think it might be for that but I can't remember. Maybe turn that off.
On another note you should look into 'Session Buddy', the Chrome extension. With another extension called 'Download Chrome Extension' you can download and install extensions from the Chrome Store into Opera and run them natively. Its a wonderful little session tool that allows you to both save sessions manually and also saves them for you automatically on a timer in case something crashes on you. This least you quickly get back to what you were doing without having to write down all the tabs you have open. Its great at works almost as well as the old sessions feature from Opera 12.

After a few days, my session.db is now up to about 120MB, and Opera is starting to get frequent momentary pauses. For example, while typing this, the text will stop for 2-4 seconds (~1 word), about every 10-15 seconds (~5 words).
It's obviously some kind of bug. I hope somebody sees this and takes a look into the problem.
I'm currently using 26 Stable too. But it's been going on for several versions... it just wasn't until recently that I figured out what does it.
(I'm the same Guido as the OP. This account was having trouble before.)

So we're on Day 3 now, after blowing away the session.db, and it's basically back to full slowness. 5-10 second long frozen pauses, in between brief periods of functionality. It makes it very hard to type this paragraph
I don't understand... if I can now reproduce this happening by just leaving the browser open for 3 days, how has the development team not discovered it? Is there a way I can forward it to them as a bug, or get in contact with them, so that I could send them a copy of the session.db's it creates for analysis?

Maybe because nobody has left Opera opened for a period of time long enough to make the issue happens? Although i guess something like that was already reported.

You can fill a bug report here.

I do leave Opera running, but I do also periodically close it. So it's not a biproduct strictly of running for an extended period, since closing it doesn't reset the problem. It could be a product of total uptime though.
I'll submit a bug report. Thanks for the link.

Neither... Every several days I delete the session.db, using the "Download Chrome Extension" and "Session Buddy" plugins (mentioned above) to restore my tabs. That buys me several more days of smooth sailing.
Hopefully the devs take my bug report seriously, and fix this thing. It's blatantly reproducible, on a couple different machines I use. I've been using Opera since the beginning, and I really don't want to have to switch.

Ah ok thanks. I am having the same problem. I have just been deleting session.db and then letting it recreate.
Edit: Which I've just realised doesn't save my tabs. Nevermind

I can't recommend Session Buddy enough. You really should try it. Its a much better way to save your tabs, especially if Opera or your system crashes.

Session Buddy will save your tabs. So the workaround goes like this...
- Have "Download Chrome Extension" and "Session Buddy" plugins installed.
- Have Opera running.
- Go to Session Buddy, and save your session.
- Close Opera.
- Delete the following files, manually (Win7):
- C:\Users\YOURUSER\AppData\Roaming\Opera Software\Opera Stable\session.db
- C:\Users\YOURUSER\AppData\Roaming\Opera Software\Opera Stable\session.dbak
- C:\Users\YOURUSER\AppData\Roaming\Opera Software\Opera Stable\session.db-journal
- Reopen Opera. All tabs will be gone.
- Go to Session Buddy, and restore your saved session. It will restore all tabs, including pinned tabs.
- Use Opera for a few days, until it gets slow. Go back to Step 1.

Have you tired disabling 'Continue where I left off' in the startup options? As I said above I don't even have any sessions files and I think its because I don't use that feature. Yeah, it needs to be fixed by the devs but at least you wont have to close Opera all the time till the do track down the problem.

No, because that is an extremely important part of how I want to use Opera/browsers.

I'm on the verge of abandoning Opera for this reason.
Once the file gets large enough, Opera becomes pretty much unusable. I've been getting by using Session buddy and deleting session.db file and that work for a time but its not long before the file has grown large enough to become a problem again. -

@krrish1379 Its basically a save of every window and webpage you have open. So, when you open a previous session, it opens all of the webpages in one go. Its a feature Opera 12 had built in and its very handy for picking up where you left off. Currently it does it if you have Continue where I left off in the settings, but that only works when closing and reopening the browser. Extensions like Session Buddy can save and open sessions at any time and even keep several sessions saved at once.
@gregdray Just out of curiosity, what OS are you running and how much RAM do you have?

@lando242 Windows 8.1 Enterprise with 8gb of Ram.
I deleted the session.db file and restore my tabs this morning and already the file is back up to 79mb. I'm not sure at what size it starts to get noticeable but its somewhere around 130mb or so, most noticeable when scrolling in web pages.
