# PulseAudio memory usage plotting script
|
||
|
|
#
|
||
|
|
# Before invocation, generate necessary data by running the
|
||
|
|
# 'benchmark_memory_usage.sh' bash script. Afterwards, you can plot
|
||
|
|
# such data by running:
|
||
|
|
#
|
||
|
|
# gnuplot plot_memory_usage.gp
|
||
|
|
#
|
||
|
|
# Note! To avoid scaling issues, memory is plotted in a "double y axis"
|
||
|
|
# form, with VM usage on the left, and dirty RSS memory usage on the
|
||
|
|
# right. The scales are different.
