search for: worker_processes

Good morning, The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server. In the case of hyper-threading, should this be the number of cores or the number of threads? For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads. Would I start my worker_processes at 4 or 8? Finally, would th...

Greetings, I''m getting this - ActiveModel::MissingAttributeError: missing attribute: some_attr - on a random basis under a unicorn server, running rails 3.2 and ruby 1.9.3 As the case of the last poster in the following thread - https://github.com/rails/rails/issues/1906 - I too am able to resolve this issue by settingpreload_app to false. However, this is not the behaviour I want to

...sock, if i visit that port, the errors are rendered as normal with a 500 page, the same port, throught nginx, shows errors like you do in development. The app is rails latest (not 3), i run it with unicorn_rails -E production -c /root/pbr/current/config/unicorn.rb -D and unicorn.rb looks like.. worker_processes (20) preload_app(true) Im thinking it could be a permissions problem, the rails directory is in under root, nginx runs as user nginx, but i have given chown permission the the directory?

Hi, I would like to understand how to calculate optimal value for "pool" parameter in database.yml I''m using rails 3, ruby 2, postgres, elasticsearch, unicorn, nginx My server : 12 coeurs 24 threads ( I dont know if it is necessary for define pool value) unicorn : worker_processes 24 I have around 1500 pages requested per minutes, and around 200ms per request Is it also useful/necessary to use this ? allow_concurrency: true thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is there a way to get the number of requests that are currently awaiting to be executed by my rails app by unicorn? Or there is no queue in unicorn and I should look for this information somewhere in nginx or other front-end server? Couldn''t find much information about this topic, so decided to ask here first.

If I''m running two rails apps on the same server using Unicorn, I have to run two instances of Unicorn, right? If so, then here''s a place where passenger might win in terms of memory use, as the rails code will be loaded into memory twice, right? I''m still probably going with Unicorn, but just exploring this first. Thanks, John
