A while ago, I also was suffering from serious "unresponsiveness" when opening moderately-large Google Spreadsheets. After reading an earlier version of https://doc.opensuse.org/documentation/leap/tuning/html/book-tuning/cha-tuni... https://doc.opensuse.org/documentation/leap/tuning/html/book-tuning/cha-tuni..., I found that setting: sysctl vm/watermark_scale_factor=1000 from its default value of 10 greatly improves performance in these situations. At first, I was concerned that it would increase swapping/paging, but it does not. All it does is run kswapd more often to identify free pages. That's additional CPU overhead, but it's not noticeable with today's multi-core systems. I haven't noticed anything negative by making this change. Does anyone have any warnings for me?

Could some Chromium users report whether it is working or whether it crashes the whole system due to OOM. Seen 4 reports of this on Reddit. I have 8GB of ram most of it taken by Chromium, Firefox, and Evolution. It does not crash but sometimes there is big memory pressure leading to stalls until I close some tabs with 'web application' style pages.
When that happens the browsers also sometimes actively flag random pages as 'unresponsive' offering to terminate the related processes.
All in all I think it should not happen.
I am using Tumbleweed on this small machine. With Leap I see no problems either but there is much more RAM available, too.
Thanks
