我有几个运行 Win2k8R2 和 IIS 7.5 的 IIS 服务器。每当我打开 inetmgr 并展开服务器节点时，在我可以做任何事情之前都会有大约 2 分钟的延迟。一旦服务器节点扩展，我就可以正常执行所有任务。我还有其他具有类似设置的离线服务器，它们几乎可以立即扩展服务器节点。
在有问题的服务器上使用“netsh tracing set trace ...”运行跟踪后，我看到他们正在尝试访问 Microsoft CRL 文件，这显然会超时并导致缓慢。在良好的服务器上，没有网络痕迹。
有没有人知道什么会导致这个问题以及为什么我的所有服务器上都没有这种缓慢？我猜其他管理员搞砸了某个地方，但找出哪里会很痛苦。
这是我的跟踪文件以备不时之需:)

这与我在此处描述的问题相同: http://forums.iis.net/t/1222164.aspx?IIS+manager+slow+node+opening
在我的例子中，服务器阻止了所有传出流量，因此它无法到达 crl 服务器。
使用 Internet 选项/连接/LAN 设置部分修复了它，我打开了(为您的 LAN 使用代理服务器)-> localhost:9000。这样请求会更快超时。
IIS 管理器中的节点打开速度更快。 (7-10 秒)之前(20-30 秒)。

我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0
我想安装一个带有一些身份验证的私有(private)Rubygem服务器。我希望能够使用公共(public)Ubuntu服务器托管内部gem。我读到了http://docs.rubygems.org/read/chapter/18.但是那个没有身份验证-如我所见。然后我读到了https://github.com/cwninja/geminabox.但是当我使用基本身份验证(他们在他们的Wiki中有)时，它会提示从我的服务器获取源。所以。如何制作带有身份验证的私有(private)Rubygem服务器？这是不可能的吗？谢谢。编辑:Geminabox问题。我尝试“捆绑”以安装新的gem..
我打算为ruby脚本创建一个安装程序，但我希望能够确保机器安装了RVM。有没有一种方法可以完全离线安装RVM并且不引人注目(通过不引人注目，就像创建一个可以做所有事情的脚本而不是要求用户向他们的bash_profile或bashrc添加一些东西)我不是要脚本本身，只是一个关于如何走这条路的快速指针(如果可能的话)。我们还研究了这个很有帮助的问题:RVM-isthereawayforsimpleofflineinstall?但有点误导，因为答案只向我们展示了如何离线在RVM中安装ruby。我们需要能够离线安装RVM本身，并查看脚本https://raw.github.com/wayn
我正在编写一个包含C扩展的gem。通常当我写一个gem时，我会遵循TDD的过程，我会写一个失败的规范，然后处理代码直到它通过，等等......在“ext/mygem/mygem.c”中我的C扩展和在gemspec的“扩展”中配置的有效extconf.rb，如何运行我的规范并仍然加载我的C扩展？当我更改C代码时，我需要采取哪些步骤来重新编译代码？这可能是个愚蠢的问题，但是从我的gem的开发源代码树中输入“bundleinstall”不会构建任何native扩展。当我手动运行rubyext/mygem/extconf.rb时，我确实得到了一个Makefile(在整个项目的根目录中)，然后当
最近，当我启动我的Rails服务器时，我收到了一长串警告。虽然它不影响我的应用程序，但我想知道如何解决这些警告。我的估计是imagemagick以某种方式被调用了两次？当我在警告前后检查我的git日志时。我想知道如何解决这个问题。-bcrypt-ruby(3.1.2)-better_errors(1.0.1)+bcrypt(3.1.7)+bcrypt-ruby(3.1.5)-bcrypt(>=3.1.3)+better_errors(1.1.0)bcrypt和imagemagick有关系吗？/Users/rbchris/.rbenv/versions/2.0.0-p247/lib/ru

这似乎非常适得其反，因为太多的gem会在window上破裂。我一直在处理很多mysql和ruby-mysqlgem问题(gem本身发生段错误，一个名为UnixSocket的类显然在Windows机器上不能正常工作，等等)。我只是在浪费时间吗？我应该转向不同的脚本语言吗？ 最佳答案 我在Windows上使用Ruby的经验很少，但是当我开始使用Ruby时，我是在Windows上，我的总体印象是它不是Windows原生系统。因此，在主要使用Windows多年之后，开始使用Ruby促使我切换回原来的系统Unix，这次是Linux。Rub
我想在Ruby中创建一个用于开发目的的极其简单的Web服务器(不，不想使用现成的解决方案)。代码如下:#!/usr/bin/rubyrequire'socket'server=TCPServer.new('127.0.0.1',8080)whileconnection=server.acceptheaders=[]length=0whileline=connection.getsheaders想法是从命令行运行这个脚本，提供另一个脚本，它将在其标准输入上获取请求，并在其标准输出上返回完整的响应。到目前为止一切顺利，但事实证明这真的很脆弱，因为它在第二个请求上中断并出现错误:/usr/b
您如何在Rails中的实时服务器上进行有效调试，无论是在测试版/生产服务器上？我试过直接在服务器上修改文件，然后重启应用，但是修改好像没有生效，或者需要很长时间(缓存？)我也试过在本地做“脚本/服务器生产”，但是那很慢另一种选择是编码和部署，但效率很低。有人对他们如何有效地做到这一点有任何见解吗？ 最佳答案 我会回答你的问题，即使我不同意这种热修补服务器代码的方式:)首先，你真的确定你已经重启了服务器吗？您可以通过跟踪日志文件来检查它。您更改的代码显示的View可能会被缓存。缓存页面位于tmp/cache文件夹下。您可以尝试手动删除
