README file from "Disk.perf.disk" directory 

The data files contained in this directory accompany the showcase 
files up one directory in toolbox/perfTuning/ChallengeIO.

The files are:

	a) lvres.* files are the logs of multiple runs of sio.
		These files show the sio parameters used for the runs.

		1) 1vs4 shows 1 segment versus 4 segments.
		2) bvst shows write buffered versus write through.
		3) step shows varying step size performance.

	b) graph_* are scripts that process lvres.* files and average
		the numbers from the same runs and produce tables
		of the performance (the perf.* files) and shell scripts
		that invoke xgraph to display the data graphically
		(graph.*).
		The graph_* files generate the perf.* and graph.* files
		from the corresponding lvres.* files.

	c) perf.* files contain tables showing varying read/write/create
		performance with raw/direct/efs.

		- From graph_1vs4 lvres.1vs4 - 1 versus 4 segment
		1) dw1 - direct, 1 segment
		2) dw4 - direct, 4 segment
		3) ew1 - efs, 1 segment
		4) ew4 - efs, 4 segment
		5) rw1 - raw, 1 segment
		6) rw4 - raw, 4 segment

		- From graph_bvst lvres.bvst - write buffered vs write through
		1) dwb - direct, write buffered
		2) dwt - direct, write through
		3) ewb - efs, write buffered
		4) ewt - efs, write through
		5) rwb - raw, write buffered
		6) rwt - raw, write through

		- From graph_step lvres.step - step size variation (1 vs 4 seg)
		1) 1seg - 1 segment
		2) 4seg - 4 segment

	d) graph.* files are shell scripts that invoke xgraph with the
		appropriate data, titles, axes, etc. The following
		are present:

		- From graph_1vs4 lvres.1vs4 - 1 versus 4 segment
		1) dw1 - direct, 1 segment
		2) dw4 - direct, 4 segment
		3) ew1 - efs, 1 segment
		4) ew4 - efs, 4 segment
		5) rw1 - raw, 1 segment
		6) rw4 - raw, 4 segment
		7) c - create performance for direct and efs.
		8) r - read performance for raw, direct and efs.
		9) w - write performance for raw, direct and efs.

		- From graph_bvst lvres.bvst - write buffered vs write through
		1) dwb - direct, write buffered
		2) dwt - direct, write through
		3) ewb - efs, write buffered
		4) ewt - efs, write through
		5) rwb - raw, write buffered
		6) rwt - raw, write through
		7) bc - create performance for direct and efs.
		8) br - read performance for raw, direct and efs.
		9) bw - write performance for raw, direct and efs.

		- From graph_step lvres.step - step size variation (1 vs 4 seg)
		1) sc - create performance for 1 and 4 segment.
		2) sr - read performance for 1 and 4 segment.
		3) sw - write performance for 1 and 4 segment.

	e) ps.* files are postscript files for the graphs drawn by the
		graph files.
		
		1) The ps.14.* files are the graphs generated from
			"graph_1vs4 lvres.1vs4".
		2) The ps.bt.* files are from "graph_bvst lvres.bvst".
		3) The ps.24.* files are from "graph_step lvres.step",
			and are the results of varying step sizes on a
			24-way stripe with 1 and 4 cache segments.
