Interesting. I wonder if the fact that x86 machines have a 4kB page size matters here. It seems hard to be sure because it's not something you can really change. But there are a few of your graphs where 4kB spikes up above any higher or lower value, and maybe that's why? -- Robert Haas EDB: http://www.enterprisedb.com
