You need to rescale for 2008; people often have 4GB or more RAM in their machines ... hell, I have one machine here from 2002 with 14GB in it (I don't power it up very often because it's too noisy). The test was only writing 1GB of data, which would fit in the page cache of my laptop, never mind the kind of machine that's likely to have an 8-way array attached to it. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
