Does anyone have this issue were firefox becomes slow if left open for a long time. In my case after a couple of weeks rendering becomes slow and when I use youtube for example if is laggy, just trying to change volume taka few second to show the volume bar. It also happens to my laptop at work. I have around 30 tabs open.
My laptop with a non-critical service: Uptime: 9 weeks, 5 hours, 34 minutes
I’ve had Debian VMs run for long periods of time without me touching them. They normally would have high uptime unless it automatically reboots to apply a kernel update. The key is these are virtualized servers. You should absolutely avoid running to long without a reboot. The longer you wait the greater the chance of something breaking on the next boot. There is also the issue of memory fragmentation but that’s not really an issue these days.
