POngx_pagespeed - Gzip static assets
text
Body
copied!<p>I am trying to find the best approach for my nginx box. My goal is, of course, the best possible performance, and the best loading times for my users.</p> <p>So I was load testing my nginx and - with the help of maxim-dounin from nginx forums - found out that my throughput problems was on the fly gzipping of static assets.</p> <p>I'll have to pre-gzip everything on the build process, thats very easy - and do on the fly gzip for dynamic content only with comp level @ 1 or 2, that shoud save some cpu and allow me to serve as many users as possible with aws m1.small ec2 instance.</p> <p>But I also intent to use ngx_pagespeed to optimize these static assets, minify, combine, stuff that ngx_pagespeed does so well. I mean, images I can work around and do jpgoptim and pngoptim on build process, but combining css/js is harder.</p> <p>I am using these ngx_pagespeed config:</p> <pre><code>pagespeed on; pagespeed EnableFilters combine_css,combine_javascript,canonicalize_javascript_libraries,collapse_whitespace,convert_meta_tags,dedup_inlined_images,flatten_css_imports,inline_import_to_link,inline_css,inline_javascript,rewrite_javascript,remove_comments,rewrite_css,rewrite_images,convert_gif_to_png,recompress_png,convert_jpeg_to_progressive,strip_image_color_profile,strip_image_meta_data,insert_image_dimensions; pagespeed JpegRecompressionQuality 80; pagespeed FileCacheSizeKb 256000; #256mb pagespeed FileCacheCleanIntervalMs 3600000; pagespeed FileCacheInodeLimit 500000; pagespeed FileCachePath /run/shm/nginx/pagespeed_cache; pagespeed Statistics on; pagespeed StatisticsLogging on; pagespeed LogDir /var/log/pagespeed; pagespeed LowercaseHtmlNames on; </code></pre> <p>Any ideias on how ngx_pagespeed works with nginx gzip_static? I mean, as far as my understaing go, ngx_pagespeed is running 'in front' of nginx, as it caches everything it optimizes to tmpfs. If the server got a hit for a already optimized asset it servers from tmpfs, and I looked for gzipped files on the cache folder and could not find any. First of all, ngx_pagespeed does its own gzipping? It does it on the fly or it cache gzipped version?</p> <p>How does it go when it receives an already gzipped asset from nginx (gzip_static on)? Does it have to unzip and then gzip again after optimization?</p> <p>How can I have the best of both worlds - serving pre-compressed static assets and ngx_pagespeed optimizations?</p> <p>Thanks alot and best regards.</p>
