You can always ask some help on git@vger.kernel.org.Personally I have been following the development of git from a technical point of view out of interest, but at the moment I do not have a linux box unfortunately so I have not been able to play with it. It also has a tool (gitk) that visualizes merges etc.)
What I can say is that from a usability point of view it is very fast (that was Linus' number one design rule when he wrote git)For download performance it is probably important to pack the repository before checking out from a client. Pack files are supposed to help a lot with regards to network performance if I understand correct.

Which projects use git? (X.org e.g.)http://git.or.cz/gitwiki/GitProjectshttp://freedesktop.org/wiki/UsingGit

Hope this is of help to some.DènisOn 8/16/06, Eugen Minciu [EMAIL PROTECTED] wrote:

then thats fine. but its server-side we really care about here - remember :)Well ... it was client side, but it didn't work as I couldn't find a way to send the files to the bit bucket with either svn or git.
word seems to have it that git is da shitsnizzle when it comes to performance - but i am going to want to see the numbers. how many clients can connect and checkout and/or update and how long does it take vs. the load on the server etc.
Well I oficially declare my numbers crap. I hold my laptop responsible for this mess and I don't really trust a single number here. And I'll explain why in a minute.Here are the numbers, but as I said, I really don't think they should be considered usefull. Consider this to be FUD.
CVS:- CPU Load: Max- Mem Load: 45%- Checkout Time: 296.374sSVN:- CPU Load: 20% ( It was 20% in the last test as well I believe, all processes seem to share the same CPU usage.)- Mem Load: 40%
- Checkout Time: 658.576SVN/HTTP:- CPU Load: 70-90%- Mem Load: 60%- Checkout Time: 874.618GIT (git protocol):- CPU Load: Max- Mem Load: 10-15%- Checkout Time: 2345.243GIT (http):
- CPU Load: 5%- Mem Load: 10-12%- Checkout Time: A lot, from what I could see, it was cloning at a very low rate.I used actual disk access on both the client and the server, Apache2-mpm-worker, SVN with FSFS and that's about it. A spec of machines would be missing the point. The point is they aren't any good for these kinds of benchmarks.
It looks really suspicious to me that times seem to increase linearly among the tested SCMs, even though this wasn't the case in the first test.Also, I often found network traffic dropping to 0 because the laptop's HDD couldn't take the heat anymore.
Also, the version of the script I tested with did not wait after one SCM finished and moved directly to the next one. I don't think that was a good idea.Now, Git with http was excellent in terms of CPU Memory usage but I'm not really sure why it wouldn't go past
1.5MB/s (ever). It would have probably taken me an hour or so, and that's on a LAN which is pretty much unacceptable.But here's the script. Feel free to change the number of threads at the top of the script (it's currently at 20) but please make note that you need about 180MBx number of threads available.
Change the lines near the top to specify how the checkout commands should be run in your environment. If you want to add another test but lack the Ruby know-how just tell me what you need and I'll patch it up for you.
Finally make a new directory, copy the script there and execute 'ruby scm_benchmark.rb'. And that's it.So ultimately I urge someone with more patience and two solid machines to give my little test a spin. Please don't make any decision based on my data. Pretty please! And Carsten, if this doesn't turn you on, I'm sorry ;)
