POServing precompiled assets with nginx
text
Body
copied!<p>Is it possible to serve precompiled assets with nginx directly? Serving assets dynamically with Rails is like 20 times slower (4000 req/sec vs 200 req/sec in my virtualbox).</p> <p>I guess it can be done with some rewrite rule in nginx.conf. The problem is, however, that these filenames include md5 hash of the content, so I don't really understand what can be done with this.</p> <p>If its not possible I don't get the whole idea with Rails 3.1 asset pipelines. Reducing client bandwidth and page load time at the cost of x20 server load?</p> <p>Any ideas?</p> <p>UPD: So, I managed to setup my nginx and Rails in a way, when <strong>everything</strong> in my application is served at the speed of ~3500-4000 requests/sec.</p> <p>First of all I added two virtual hosts, with one serving as a caching proxy to another and discovered that assets are served at the speed I wanted (4k). Then I connected my Rails application with memcached (nothing special so far, just one line in application.rb: <code>ActionController::Base.cache_store = :mem_cache_store, "localhost"</code>)</p> <p>Then I added things like <code>expires_in 1.hour, :public => true if !signed_in?;</code> to my controllers to change default caching policy of Rails content and got speed boost around 500 requests/per second for my dynamic pages (before that it was something close to 200, and it was ~50 before I ever started this all).</p> <p>Now, when my nginx config files look like this:</p> <p>nginx.conf:</p> <pre><code>... proxy_cache_path /tmp/blog keys_zone=one:8m max_size=1000m inactive=600m; proxy_temp_path /tmp; gzip off; include /opt/nginx/conf/sites-enabled/*; </code></pre> <p>sites-enabled/blog:</p> <pre><code>server { listen 8080; server_name blindsight; root /home/mike/rails/blog/public; rails_env production; # serve static content directly location ~* \.(ico|jpg|gif|png|swf|html)$ { if (-f $request_filename) { expires max; break; } } passenger_enabled on; location ~ /\.ht { deny all; } } </code></pre> <p>sites-enabled/main:</p> <pre><code>server { listen 80; server_name blindsight; location /authorize { proxy_pass_header Cookie; proxy_pass_header Set-Cookie; proxy_pass http://127.0.0.1:8080; } location /admin { proxy_pass_header Set-Cookie; proxy_pass_header Cookie; proxy_pass http://127.0.0.1:8080; } location / { root /home/mike/rails/blog/public; # All POST requests go directly if ($request_method = POST) { proxy_pass http://127.0.0.1:8080; break; } proxy_redirect off; proxy_pass_header Cookie; proxy_ignore_headers Set-Cookie; proxy_hide_header Set-Cookie; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_cache one; proxy_cache_key blog$request_uri; proxy_cache_valid 200 302 5s; proxy_cache_valid 404 1m; proxy_pass http://127.0.0.1:8080; } </code></pre> <p>Everything is fast like a bloody lightning :) Thank you, guys.</p>
