Computer slows down?

[GregM]

This doesn't always happen but it's curious when it does.

Sometimes...
...as the day goes on the response time of things like... mouse hovering over, clicking on things, typing on the keyboard, can start to take longer and longer to respond.
Usually I reboot and that fixes it.

Any ideas on what can cause this?

When that happens on my computer, its usually a browser (99% of the time Firefox) that is either leaking memory or has an unresponsive script running. I usually kill the browser if possible and that clears it up.

Restart browser, maybe a re-boot (which is kind of drastic), or I usually do a "Ctrl-ALT-Backspace" key combination, which on my 14.04 restarts the Desktop/KDE, and that freshens things up. I'm not sure, but maybe also try clearing the caches and such, like running Bleachbit ( a cleaner for Linus/Ubuntu), or at least clear out the caches in your browser(s).

Kind of what I was expecting.
Thanks guys

Sounds like something eating up your I/O times.. Are your Ram, or Disk(s) doing anything unusual when this happens?

Not that I am aware of.
Is there a way to tell? Somewhere to look?

Sounds like full memory and swapping. Next time you're on there for awhile, open a terminal and type "free" and leave the terminal window open, then when it slows down, type "free" again and see if swap is in use. There's been several plasma widgets that have memory leaks - meaning they eventually fill memory with garbage. Ksysguard will show this also.

Instead of rebooting, try logging out and back in.

That's a pretty slick little program

I'm currently using FF 60.1. I've experienced slowdowns while using FF and after closing it. When I look at the services some zombie FF threads are still running. I kill them and things return back to normal. I've noticed that behavior since FF 54, IIRC.

FF 60.1 also, on occasions and for unknown reasons, fails to bring up a tab on a known and existing website and displays the following:


Once that tab image appears retrying is not useful. Even copying the URL and opening another tab and pasting that URL in fails. The only way I've found is to "copy link location", open an empty tab, and paste the link location into the URL.

FWIW, in Kubuntu bionic I've got firefox 61.0, since the 6th of July. No mention of memory fixes in the release notes.

This morning after I booted up I noticed an upgrade notice in the system tray. It was FF 61.0.1 I'm running it now. My biggest problem with FF 60 was when I opened a link in a new tab it often crashed the tab. I'm watching for that misbehavior in this release.
