Timestamps on the traces are accurate to under a millisecond. For more details, contact the author, or visit <URL:http://www.dcs.uky.edu/~randy/Research/index.html>. - Chris Ruemmler has done a study on low-level disk access patterns for a workstation, a server, and a time-shared system which appeared in the Winter 1993 USENIX proceedings. A copy may be obtained via anonymous ftp from <URL:ftp://ftp.hpl.hp.com/wilkes/>. - Stephen Russell <smr@cs.unsw.oz.au> has instrumented the SunOS 4.1.x kernel running on Sun 3 machines. The system allows time-stamped event records to be obtained from various points in the kernel. Events can be categorised (eg, paging, file system, etc), and are read via pseudo-devices. Ioctl calls allow substreams to be enabled/disabled, buffer status checked, etc. An external high resolution timer is used for timestamping. - [93-05-09-09-23.32] The traces used in `Measurements of a distributed file system' (SOSP 1991) may be obtained from <URL:http://now.cs.berkeley.edu/Xfs/SpriteTraces>.
