They're highly IO bound, and barely use 10-20% of their old 2.4Ghz Prestonia Xeon CPUs. It's hard to justify junking those machines < 5 years. We have a couple of 6G machines and some 8G machines using PAE. On the whole, they actually have been working really well (hmmm, apart from the recent dirty pages issue + reiserfs data=journal leaks + inodes in lowmem limits) Rob - 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/
