Hi,
Does anyone knows how to set concurrency=true for mongrel. For webrick
we can set that in lib/webrick_server.rb at
line 80 :
REQUEST_MUTEX.lock unless ActionController::Base.allow_concurrency
Is there something similar possible in mongrel, and where?

Don''t do it. Rails is not thread safe, you will get all kinds of problems.

Hi Shishir Andreas is right, Rails is single-threaded and that''s why the recommended approach is to use Apache to proxy Rails and handle the static content in front of a pack of mongrel processes.

- Mongrel serves static files directly, without telling rails anything about it. - You will need to find rails handler in mongrel source, rails_handler.rb iirc and disable mutex around request serving part, and also set ActionController::Base.allow_concurrency = true in your environment file. - Don''t do it if you don''t know what you''re doing :-) - Have fun.

But in my context the two concurrent requests retrieve dynamic content from the server and are getting locked because I don''t know. Whether it''s because of rails or because of mongrel. :( , badly confused now SOS !!

Serving a static file doesn''t keep a mongrel process busy due it''s threaded model, unless of course you''re doing it from rails using send_data/send_file ( which you should never ever do ).> It''s because one mongrel can only serve one rails request at a time.

Depends on how many people will be using your site at once. I use send_data just fine with the software I have written for a small lab.
