I'm answering the question '2.4 without swap' - Yes. It is. Works. No problems. 'Paging like crazy' became for me a synonym of Linux. It doesn't matter how much memory you have. Less == worse. Developers stopped testing VMM regression on low-memory computers long time ago. We have now fashion for clusters and numas. And a lot of swap on very fast raids. After all it is cheap. Just couple of thousands greenbacks. It was really funny when developers on LKML were sugesting to buy another hdd for swap. Very funny. Unfortunately I'm not a specialist in VMM... As I see there is not that much edge case testing going around. -- Ihar 'Philips' Filipau / with best regards from Saarbruecken. -- "... and for $64000 question, could you get yourself vaguely familiar with the notion of on-topic posting?" -- Al Viro @ LKML - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
