Hi,
I’m wondering if there is any feature that combines all/multiple javascripts into one and highly reused images using css sprint?
I do see it takes bit of time to load the website during the first time and then is very fast from second load onwards.
Any recommendation?

If you are using our [official install](https://meta.discourse.org/t/142537?silent=true) and have SSL enabled (eg access your site with http **s** ://yoursite.com) then you get HTTP/2
This means we send all the assets more efficiently and that sprites for avatars and various other hacks that were needed in the HTTP/1.1 era are no longer beneficial.

Ah yea I understand. Never thought http2 comes by default with the discourse DO image/installation script.
I’m not an advance in this tech stack, I did wonder why there is a mix of h1.1/h2 request. Is it a browser choice?
Also, to reduce the time for first page load, is there a topic/discussion here about page optimisation/cdn/server side settings to read about specifically for discourse?
I have 7 to 10 seconds loads time in a private window and it’s a vanilla setup and a small forum.

Also, If there is a blog/category section, I would love to read about engineering/scalable decision that the discourse team made while building the forum.

You can search on scaling and scalability using the magnifying glass above. 😉
You can also find links to codinghorror’s blog from posts he shares here in the #site-feedback:blog subcategory .
This is a really useful post on a related topic that you might miss:

> Number of posts made is about the least interesting metric, even more so over such a long time period. Page views is far, far more relevant for determining needed resources. It can be a bit tricky to compare the requests and traffic patterns of a “traditional” mostly-server-generated forum to a Discourse forum, because Discourse is very API-driven, so we often serve multiple HTTP hits per “page view”, but we tend to service each HTTP request a lot quicker, so the forum appears to be a lot more…

If you pay attention to your print screen you will see the lines showing HTTP1.1 aren’t real requests, but just resources coming from cache.
