There is a shop on Opencart. The product page has a large range of options, as a result, we have 1000 simultaneous GET requests when loading a page with thumbnail images - the images themselves are submitted via CDN. The loading of the page is delayed - the search suggests that Nginx tuning is needed, but the use of various configs did not help much. I need advice on where to dig.

ps In the config there can be a lot of excess, or vice versa - I ask without much indignation, he experienced a sea of ​​transformations :)

  • Hmm, do you get php pictures? - vp_arth
  • Maybe a few bottlenecks - 1. generation of thumbs on the fly, then you need server caching 2. not satisfied that with F5 the page is overloaded for a long time - client caching 3. not that, not the other, you want to load faster - more compression of images and / or HTTP2. Choose. Ps. If you don’t want nginx to climb up to an Indian behind pictures, use this location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|bmp|txt)$ { access_log off; expires 14d; break; } location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|bmp|txt)$ { access_log off; expires 14d; break; } location ~* ^.+\.(jpg|jpeg|gif|css|png|js|ico|bmp|txt)$ { access_log off; expires 14d; break; } - Total Pusher
