I use a light weight window manager and its pretty common for my browser on its own to be above 8GB, if you end up with an electron app or two which are pretty common these days then its pretty easy to be hitting 16 already. I don't think I could have a functioning desktop with under 32GB to not be occasionally hitting issues. Having said that my machines are currently comfortably sitting at 11Gb and 13Gb running mostly general desktop workloads atm.
Having hit the OOM reaper this week, I wonder if your browser observation is perhaps an example of a generalisation of Parkinson's law? The browsers consume until stopped. In my case competition against a freshly launched 4GiB VM in a system with 16GiB of physical memory triggered the OOM reaper. Not sure why OOM killer targetted plasmashell with a score of 0 this week, instead of one/many of the 34 chrome(ium) instances with a score of 300, or another 8 chromium instances with a score of 200, eg: Nov 30 14:57:18 chunk kernel: [ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name Nov 30 14:57:18 chunk kernel: [ 17992] 507 17992 4366216 2998934 26849280 35029 0 plasmashell Nov 30 14:57:18 chunk kernel: [ 2515] 507 2515 296308145 15562 1798144 10297 300 chrome Nov 30 14:57:18 chunk kernel: [ 18647] 507 18647 8566333 6256 1388544 3418 200 chrome The journal reminds me it did the same in August too. My bad. Daniel
