A survey conducted in September 2014 found that only 20% of organizations have a strong knowledge of HTTP/2, with a third having implemented or piloted it. Larger organizations are more likely to adopt HTTP/2 and SPDY, driven by the need for better performance and efficient resource use. The main barriers to adoption include low availability of services and lack of familiarity with the technology.
