Question

Why does the site load much slower when switching from an http domain to https?

Viet Nguyen Duc 20

When I switched from http domain to TLS encrypted https, the site loading speed was slow. When I perform the function of uploading files or checking in documents to Document Library, sometimes an error screen is displayed.

We have not found the cause of the error. Are we missing any TLS settings for https domains?

Thank you for the answer. I understand your answer. I ask one more question as follows: why when I use https domain do issues related to machineKey often occur when uploading files? My current document library has more than 10,000 items.

Compare with HTTP, HTTPS adds a layer of encryption using SSL/TLS. When you access a website with HTTPS, your browser and the server establish a secure connection. All data transmitted between the two is encrypted, making it nearly impossible for malicious actors to intercept and decipher the information. So, it always be slightly slower.

There are many possibilities for sites load much slower with HTTPS, such as CPU, software, browser capability.

As a try, you could increase CPU to make sites load much quicker.
