Rails 5 very slow startup on Windows

Question

I have installed RoR 5 in my laptop

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

I started working on a project which i wanted to specificaly test under windows , and i noticed some lags and latency.

So i started a new rails app , to rule out my code , and the latency was the same.

I also tested Webrick and the latency is still there.

Im talking about 28 seconds !!!

I know there are many relative issues but most talk about rails in earlier versions.

The main reason i wanted to program this app in rails , is to run in a local server , but the user has windows on his machine...

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

Very big time gap here close to 25 seconds

*** 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

as you'd expect this performance continues throughout the page..

Any ideas? am i missing something? any of you guys developing rails 5 on windows? any tips?

I also tested on my main machine

• 16gb low latency ram
• ssd
• AMD FX8350

same slow response , but a little faster than the laptop!

Also weird thing is that , if i run the rails console side by side , i see the rails log printed in the console , but the browser loads for a long time!

I thought it was a browser problem , so to rule that out , i browsed the site by another of my local machines , so i can only use the server and not the Windows browser... still no avail , the response time is really slow!

this is Puma on the fast machine

Thank you all guys for trying to help me , i tried the solutions with no avail .. seems like rails just wont do it (yet?) ...

Nothing seems to provide a good development environment , i advised the client to use it online ..

Im uploading a video showing this issue.

• Update after trying Ruby 2.3

There's a world of problems when you try to install ruby 2.3

• SSL errors about https://rubygems.org (you have to go http://)
• sqlite3 error 1 (path in rakefile)
• sqlite3 after fixing error 1 , error 2 presents an error about sqlite3 adapter.

Found no solution regarding error 2 and stopped trying...

maybe ill switch to PG , only to see if the performance is better and mark this as solved , this requires a bit of time , so ill do it when i have some :)

Thanks!

Answer 1

One cause of the slow boot times could be OpenSSL.
See the discussion here:

OpenSSL causing very slow Rails boot time on Windows

Also read this answer for a possible temporary solution:
https://stackoverflow.com/a/36629699/823617

Here's a Rails ticket discussing the issue:
https://github.com/rails/rails/issues/25805

According to this ticket, the OpenSSL issue has now been fixed in Ruby 2.3:

Answer 2

I haven't looked at this at all myself but you could potentially try using the new built in Ubuntu that's part of Windows 10. It's in beta though so YMMV. I would test it out by seein if you can firstly install a ruby version manager (like rvm.io) as if that runs your app is likely to run.

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

At least then you are much closer to a true posix style terminal.
