It WAS NOT a bug. It was a deliberate decision by Linus, and it was explicitly pointed out in the release notes.
Fine, change bug=>recommendation.
Which means it has EVERYTHING to do with issue, Sorry, it's still over 10 year old advice.
I ran linux with 0 swap for years (from 2.0->to at least the late 2.6 series -- never crashed from lack of swap). Somewhere around then I read what linus said he used at home -- a small swap to allow for early pages that were used at boot to be swapped out (even w/o swap pressure). Now... and since 2006, I use an 8MB swap. When I first switched to that, it would get as much as 100K usage. But that seems to have fallen off, as now, with system uptime @ >3 months, I have 0 swap usage. W/enough memory swap isn't necessary for most users. When I had swap -- if it was ever used, it was a mandate: GET MORE RAM. You'll waste far less time in your life not swapping. The extra cost for ram is more than compensated by the extra time you'll have in your life. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
