Rails 5在Windows上啟動非常慢

Question

我在筆記本電腦上安裝了RoR 5

• Windows 10
• SSD
• 4gb ram
• i5 5thgen

我開始研究一個項目，我想在Windows下進行特定測試，我注意到了一些滯后和延遲。

所以我開始了一個新的rails應用程序，以排除我的代碼，並且延遲是相同的。

我還測試了Webrick ，延遲仍然存在。

我說的是28 seconds ！

我知道有很多相關的問題，但大多數人都談論早期版本的rails。

我想在rails中編寫這個應用程序的主要原因是在本地服務器上運行，但用戶的機器上有windows ...

C:\Users\John\railstestapp\testapp>rails s
=> Booting Puma
=> Rails 5.0.0.1 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options

非常大的時間差距接近25秒

*** SIGUSR2 not implemented, signal based restart unavailable!
*** SIGUSR1 not implemented, signal based restart unavailable!
*** SIGHUP not implemented, signal based logs reopening unavailable!
Puma starting in single mode...
* Version 3.6.0 (ruby 2.2.4-p230), codename: Sleepy Sunday Serenity
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://localhost:3000

正如您所期望的那樣，整個頁面都會繼續這種表現。

有任何想法嗎？ 我錯過了什么嗎？ 你們中的任何人在Windows上開發rails 5嗎？ 有小費嗎？

我也在我的主機上測試過

• 16GB低延遲內存
• SSD
• AMD FX8350

相同的慢響應，但比筆記本電腦快一點！

另外奇怪的是，如果我並排運行rails控制台，我會在控制台中看到rails日志，但瀏覽器會加載很長時間！

我認為這是一個瀏覽器問題，所以為了排除這一點，我瀏覽了另一台本地機器的網站，所以我只能使用服務器而不是Windows瀏覽器......仍無濟於事，響應時間非常慢！

這是快速機器上的Puma

謝謝所有人試圖幫助我，我嘗試了解決方案無濟於事..似乎rails只是不會這樣做（但是？）...

似乎沒有什么能提供良好的開發環境，我建議客戶在線使用它。

我正在上傳顯示此問題的視頻。

• 嘗試Ruby 2.3后更新

當您嘗試安裝ruby 2.3時會出現問題

• 關於https://rubygems.org的 SSL錯誤（你必須去http：//）
• sqlite3錯誤1（rakefile中的路徑）
• 修復錯誤1后的sqlite3，錯誤2顯示有關sqlite3適配器的錯誤。

找不到關於錯誤2的解決方案並且停止嘗試...

也許生病切換到PG，只是為了看看性能是否更好並將其標記為已解決，這需要一點時間，所以當我有一些時，生病了:)

謝謝！

Answer 1

啟動時間較慢的一個原因可能是OpenSSL。
請參閱此處的討論：

OpenSSL在Windows上導致非常慢的Rails啟動時間

Answer 2

我自己並沒有看過這個，但你可能會嘗試使用Windows 10中新的內置Ubuntu。雖然如此YMMV也處於測試階段。 我會通過seein測試它是否可以首先安裝一個ruby版本管理器（如rvm.io ），好像運行你的應用程序可能會運行。

https://blogs.windows.com/buildingapps/2016/03/30/run-bash-on-ubuntu-on-windows

至少那時你更接近真正的posix風格終端。

Answer 3

如果您不在Win 10上，我總是發現默認命令行非常平均，並且不包括許多在其他平台上被視為理所當然的事情。

我發現最簡單的方法是下載Windows的github並使用他們提供的配置終端。 （好吧，他們曾經提供過一個終端，因為我已經做了一段時間）。 值得一試如果Ubuntu方法是不行的。

Answer 4

我以前忘記提到這個，你也可以嘗試RailsInstaller http://railsinstaller.org /它是由EngineYard的人們為你設置一個完整的rails env。 不幸的是它似乎沒有活躍的Dev：/（一個加號，沒有身體報告速度作為他們的github問題FWIW的問題）

是的，我知道這令人沮喪。

僅供參考，當我以前做Windows Dev時，我個人最終安裝了虛擬機並在那里安裝了Ubuntu，這對本地開發工作正常但是“安裝一個虛擬機”並不是你想要的答案，這是大多數人這些其他選擇存在。
