# This script provides a simple way to run benchmarks against previous code and
|
|
# keep a log of how benchmarks change over time. When used with the --benchmark
|
|
# flag, it runs benchmarks from the current code and from the last commit run
|
|
# with --benchmark, then stores the results in the git commit description. We
|
|
# rerun the old benchmarks along with the new ones, since there's no guarantee
|
|
# that git commits will happen on the same machine, so machine differences could
|
|
# cause wildly inaccurate results.
|
|
#
|
|
# If you're making changes to 'gopacket' which could cause performance changes,
|
|
# you may be requested to use this commit script to make sure your changes don't
|
|
# have large detrimental effects (or to show off how awesome your performance
|
|
# improvements are).
|
|
#
|
|
# If not run with the --benchmark flag, this script is still very useful... it
|
|
# makes sure all the correct go formatting, building, and testing work as
|
|
# expected.
