SYNOPSIS
|
|
performance_tests.sh [-a] [-h] [-n number]
|
|
OPTIONS
|
|
-a excutes all the tests.
|
|
-n number executes test number
|
|
-h prints the help.

DESCRIPTION
|
|
This script is in writing. It allows you to measure memory and bandwidth usage. The first four test different cloning methods. Te following apply changes to the local remote before testing fetching and merging commands.
|
|
TEST0: classic cloning
|
|
TEST1: --single-branch
|
|
TEST2: --depth=1 --no-single-branch
|
|
TEST3: --depth=1
|
|
TEST4: sparse-checking 1M sample0 only
|
|
_________________________________________
|
|
TEST5: classic fetching and merging after addition of 1M file
|
|
TEST6: "
