# This shell script takes two `object histograms' produced using
|
|
# `histogram.pl' and prints the delta, sorted such that the objects
|
|
# that increased the most in raw memory usage are displayed at the
|
|
# top.
|
|
#
|
|
# Usage:
|
|
#
|
|
# histogram-diff.sh [-c <count>] <base> <incr>
|
|
#
|
|
# Compute incremental memory growth from histogram in file <base> to
|
|
# histogram in file <incr>, displaying at most <count> rows.
|
|
|
|
# How many rows are we gonna show?
|
|
COUNT=20
|
|
|
|
# Read arguments
