市场表现因素有多重要？ [英] How significant is the bazaar performance factor?

问题描述

我听到所有关于集市的东西都比git慢。我还没有使用太多的分布式版本控制，但是在集市网站上的 Bazaar vs. Git 上他们说大多数对绩效的抱怨不再是真实的。你有没有发现这是真的？

我听说速度可能会影响工作流程（如果X速度快，人们更可能做好事X）。 性能目前会影响bazaar与其他系统（尤其是git）的工作流程，以及如何实现这些特定情况？ 我只是试图获取为什么表现特别重要。通常当我检查或更新它时，我预计它会花费一点时间，但这并不重要。当我有一秒钟时我会提交/更新，所以它不会影响我的生产力。但是之后我还没有使用DVCS，所以也许这跟它有关系？

解决方案

Python开发人员最近决定切换到Mercurial，并作为该过程的一部分做了一些基本的git基准测试，Mercurial和Bazaar，这在。

在测试的用例中使用git或Mercurial。

这就是说，python-dev上传递的信息是所有的（git，Mercurial，Bazaar）都更好而不是Subversion，它们大部分速度都很快，而Mercurial over git / Bazaar的选择主要基于BFDL和PyCon2009参与者的直觉。

I hear all this stuff about bazaar being slower than git. I haven't used too much distributed version control yet, but in Bazaar vs. Git on the bazaar site, they say that most complaints about performance aren't true anymore. Have you found this to be true? Is performance pretty much on par now?

I've heard that speed can affect workflow (people are more likely to do good thing X if X is fast). What specific cases does performance currently affect workflow in bazaar vs other systems (especially git), and how?

I'm just trying to get at why performance is of particular importance. Usually when I check something in or update it, I expect it to take a little while, but it doesn't matter. I commit/update when I have a second, so it doesn't interfere with my productivity. But then I haven't used DVCS yet, so maybe that has something to do with it?

解决方案

The python developers recently decided to switch to Mercurial and as part of the process did some basic benchmarking of git, Mercurial and Bazaar which is documented in PEP-374.

An incredibly rough eye balling of the numbers they posted showed Bazaar to be 2-4x slower than either git or Mercurial in the use cases tested.

That being said, the message conveyed on python-dev was that all of them (git, Mercurial, Bazaar) are better than Subversion, for the most part they are fast enough and the choice of Mercurial over git/Bazaar was mostly based on the gut feelings of the BFDL and the attendees of PyCon2009.
