  1. POUpload with paperclip very slow (unicorn)
    text
    copied!<p>Sitting here with a simple rails 3 app in which I have a simple Gallery model and each gallery has many images. The image model is extended with paperclip and with the following options</p> <pre><code>has_attached_file :local, :styles =&gt; { :large =&gt; "800x800&gt;", :medium =&gt; "300x300&gt;", :thumb =&gt; "100x100#", :small =&gt; "60x60#" } </code></pre> <p>In my galleries_controller I have the following action that is implemented in order to work with the <a href="https://github.com/blueimp/jQuery-File-Upload" rel="nofollow">jQuery-File-Upload</a> plugin. thereby the json response. </p> <pre><code>def add_image gallery = Gallery.find params[:id] image = gallery.images.new({:local =&gt; params[:local]}) if image.save render :json =&gt; {:thumb =&gt; image.url(:thumb), :original =&gt; image.url} else render :json =&gt; { :result =&gt; 'error'} end end </code></pre> <p>To me this is fairly straight forward. But here comes the issue. In Development under mongrel any kind of upload works just fine with about 500-1000ms/upload. </p> <p>However when I push it in to production I constantly get timeouts of my unicorn workers and when it does send an image through it takes anywhere from 30-55 seconds for one file.</p> <p><em>the files I upload are around 100k in size</em></p> <p>I have done some testing of the bandwidth between my VPS and my dev computer witH ipref and got an average speed of about 77kbps so the upload should not be a problem. </p> <p>Note I also did a test with a non ajax file upload using the same app with user model that has an avatar. Development => Completed 302 Found in 693ms Production => Completed 302 Found in 21618ms</p> <p>Anyone experienced a similar issue with (rails3, unicorn) file uploads?</p>
