DESCRIPTION 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. This script is in writing. It allows you to measure memory and bandwidth usage.
