Glasgow disk benchmarks

I repeated the Edinburgh benchmarks testing at Glasgow. Results can be found here:

The behaviour for random reads and writes is very similar to that observed for the Edinburgh disk, although the absolute rates at Glasgow are higher. The sequential behaviour is somewhat different. A single thread gives a substantial perforamce boost for both reads and writes. Filesytem was ext2 with default options. dump2fs reported the large_file feature.
