The major changes are using rolling averages to smooth out the seek and throughput graphs, and it can generate mpgs of the IO done by a given trace. Here's a sample of the smoother graphs (creating 20 kernel trees): http://oss.oracle.com/~mason/seekwatcher/ext3_vs_btrfs_vs_xfs.png There are details and sample movies of the kernel tree run at: http://oss.oracle.com/~mason/seekwatcher -chris
