Server extremely slow?!

Hello,

for some reason my WEBrick server became extremely slow. My development server is running on a Debian system.

After some days of test writing only I started the server to do some manual testing and it took 86 seconds(!) to load the page. I was checking everything but couldn't find anything so I emptied the layout html, removed all before_filters etc. so there was literally nothing to do for the server. Took still 31 seconds to load the page. So I added the index.html back to the public folder to see if that ones taking so long to load as well. Yes, took 21 seconds to load an empty index.html. So I would say it doesn't have much to do with my application?

Does anyone know how to sort out that kind of problem?

Here's the server output: Application, nothing changed: Completed 200 OK in 2121ms (Views: 1134.9ms | ActiveRecord: 108.2ms) - IN TOTAL: 86 seconds Application, empty layout html, no before_filters: Completed 200 OK in 372ms (Views: 370.7ms | ActiveRecord: 0.0ms) - IN TOTAL: 31 seconds index.html - IN TOTAL: 21 seconds.

Thank you

Not sure why you're even bothering with WEBrick at this point, but...

Install newrelic or rails-footnotes or similar to get a better picture of where the time's being taken.

I found webrick slow on Ubuntu, mongrel works much better for me. (sudo gem install mongrel, I think, then it just goes).

Thanks, I was still on WEBrick because Mongrel caused lot of trouble on Rails 3 and Ruby 1.9.2 but I switched to thin and now 86 seconds became 3 seconds. Pretty alright :slight_smile: Still ridiculous performance from WEBrick.

I know you've already resolved your problem, but for the sake of discussion, WEBrick in it's default state is notoriously slow when being accessed remotely. You can speed it up by looking for webrick/ config.rb in your ruby's install path and changing the following:

:DoNotReverseLookup => nil

to

:DoNotReverseLookup => true

Thanks for the hint! Nevertheless I'll try to avoid WEBrick in the future :slight_smile:

Probably still couldn't stick with Mongrel, Thin or whatever even with that option enabled, right?

Thanks man! This solved here perfectly!
