mono - DNU Restore 给出大量 "HTTP request timed out"

Question

我正在尝试运行 https://github.com/aspnet/home 中的示例.
但我在更新引用文献时遇到问题。恢复速度非常慢，并且某些软件包会失败:

我尝试使用 nuget、myget、http、https 来设置不同的 url。
我检查了我的互联网连接。有一个related issue in the dnx repo ，但没有帮助。
有什么解决方法可以尝试吗？

我在 CentOS 上使用 mono 4.0.3.20。

Answer 1

解决方法如下:

export MONO_THREADS_PER_CPU=2000
