web users expect a site to load in 2 seconds or less. You have to check following areas,

Minimize HTTP Requests

  • Combining CSS/JS Files
  • Reduce the number of images you use

Utilize CDNs & Remove Unused Scripts/Files

A CDN is a collection of web servers distributed across multiple locations so content can be more efficiently delivered to users. CDNs are typically used for static content or files that do need to be touched once uploaded.

Browser Caching

Browser caching allows assets on your website to be downloaded to your hard drive once into a cache, or a temporary storage space. Those files are now stored locally on your system, which allows subsequent page loads to increase in speed.

Compress Images & Optimize Files

Keep all your images below 150KB, nothing above 1920px in width, at an average/medium/72dpi quality level. Any larger and you’ll notice the images loading very late after the page renders as well as the slow response times to user behavior.

If application delayed. Following problems may occured:

 

   1. Pictures who uploaded on web are very large.

 

   2. Upload a video on web.

 

   3. Web cache is full.

 

Solutions:

 

   1. Compreesed pictures (60 kb) uploading on webapplication.

   2. Upload video on youtube and linked on your webapplication.

   3. By optimizing caches whereby, you ensure that the browser uses local memory to cache       

        resources in order to avoid unnecessary server request.

   4. Doing away with redirects, which they require extra processing time. Server the site to 

        users directly. 

   5. Using direct buttons. Using javascript heavy plugins to manage social sharing or transfers  

        which adds bloats and extra http calls. Therefore it is advisable to use share buttons that  

        requires minimal scripting and load social media scripts asynchronously. 

   6. By use of content delivery network. Whereby CDN such as Amazon Cloudfront to reduce    

        the page load time
