为什么现在从github上clone代码超慢

方法1-克隆(Clone)源代码到本地到github.com找到自己感兴趣的项目，比如Jquery，复制项目的CloneURL在本地打开GitBash命令行窗口把复制好的CloneURL粘贴到命令行窗口并回车，执行完Clone命令代码即下载到本地GitClone[URL]方法2-

1. clone最新一个提交 ``` $ git clone --depth=1 git@github.com:atom/atom.git cloning into 'atom'... remote: counting objects: 444, done. remote: compressing objects: 100% (359/359), done. remote: total 444 (delta 20), reused 264 (delta 8) receiving objects: 100% (444/444), 2.25 mib | 7.00 kib/s, done. resolving deltas: 100% (20/20), done. checking connectivity... done. ``` 2. 更新获取完整历史版本 ``` $ git fetch --unshallow remote: counting objects: 98400, done. remote: compressing objects: 100% (27919/27919), done. remote: total 98159 (delta 68929), reused 97823 (delta 68611) receiving objects: 100% (98159/98159), 236.07 mib | 18.00 kib/s, done. resolving deltas: 100% (68929/68929), completed with 175 local objects. from github.com:atom/atom dbe15f7..7cdaaf2 master -> origin/master remote: counting objects: 7, done. remote: compressing objects: 100% (7/7), done. remote: total 7 (delta 0), reused 7 (delta 0) unpacking objects: 100% (7/7), done. * [new tag] v0.0.1 -> v0.0.1 * [new tag] v0.0.2 -> v0.0.2 ...此处省略91行 * [new tag] v0.92.0 -> v0.92.0 * [new tag] v0.93.0 -> v0.93.0 * [new tag] v0.94.0 -> v0.94.0 ``` 期间也中断过，和直接clone一样，都不支持续传。 下面的事实可以说明我这里速度有多慢： unshallow后git status一看： ``` $ git st on branch master your branch is behind 'origin/master' by 3 commits, and can be fast-forwarded. (use "git pull" to update your local branch) nothing to commit, working directory clean ```
