Here, Git is downloading the entire history rather than only the latest One place where Git is slower is in the initial clone operation. One or two orders of magnitude faster than SVN, even under ideal conditions Many of the Git times would not be affected.Ĭlearly, in many of these common version control operations, Git is Times would be even worse for SVN if that connection was slower, while Gigabit connection to the client machine. Note that this is the best case scenario for SVN-a server with no load with a Line annotation of a single file (array.c) Pull of Commit A scenario (113 files changed, 2164+, 2259-) Log of the history of a single file (array.c – 483 revs)

In some cases, the commands don't match up exactly. Git and SVN were installed on both machines, the Ruby repository was copied toīoth Git and SVN servers, and common operations were performed on both. Subversion, a common centralized version control system that is similarįor testing, large AWS instances were set up in the same availability zone. Let's see how common operations stack up against Speed and performance has been a primary design goal of Git from the start. Git is written in C, reducing the overhead of runtimes associated with higher-level languages. Git was built to work on the Linux kernel, meaning that it has had to effectively handle large repositories from day one.
With Git, nearly all operations are performed locally, giving it a huge speed advantage on centralized systems that constantly have to communicate with a server somewhere. Git makes this process incredibly easy and it changes the way most developers work when they learn it. There are ways to accomplish some of this with other systems, but the work involved is much more difficult and error-prone.

This tends to free people to try new ideas without worrying about having to plan how and when they are going to merge it in or share it with others. You can choose to share just one of your branches, a few of them, or all of them. Notably, when you push to a remote repository, you do not have to push all of your branches. Create a branch to experiment in, realize it's not going to work, and just delete it - abandoning the work-with nobody else ever seeing it (even if you've pushed other branches in the meantime). Create new branches for each new feature you're working on so you can seamlessly switch back and forth between them, then delete each branch when that feature gets merged into your main line. Have a branch that always contains only what goes to production, another that you merge work into for testing, and several smaller ones for day to day work. Create a branch to try out an idea, commit a few times, switch back to where you branched from, apply a patch, switch back to where you are experimenting, and merge it in. The creation, merging, and deletion of those lines of development takes seconds. Git allows and encourages you to have multiple local branches that can be entirely independent of each other. The Git feature that really makes it stand apart from nearly every other SCM out there is its branching model.
