HTTP 1.1 HTTP 2
Request sent and responses received were in plain text format. Messages both request and response are encapsulated in binary format, giving more protection from any unauthorized alterations.
Finds difficulty in handling whitespace, capitalization and line endings. Use binary protocols that handle elements like whitespace, capitalization and line endings more efficiently
Needs more bandwidth to process the page contents Consumes less bandwidth to display page contents
Prioritization of loading contents is not possible in HTTP 1.1 Developers have control over prioritizing / uploading content in the order of their preference.
Loads resources one after another taking time to load the contents on a page Sends multiple streams of data using single TCP connection., resolving head-of-line blocking problem in HTTP 1.1
Metadata is transferred in plain text, hence need more overhead to handle Uses header compression mechanism, that reduce overhead
HTTP 1.1 can handle only plain text, and is not compatible to process CSS, JavaScript, images, sounds, videos, and digitized smell, touch samples. Uses server push help to store resources to be used in request in browser’s cache, even before requested, displaying content quickly.
