Browser settings and performance

Depending on the browser you use, browser settings can affect the performance of your instance.

Web pages in your instance can be large, for example, over 500 kb for a long list of incidents with many columns. To speed performance, most browsers can accept compressed data from an application server so that the full 500 kb does not have to be sent over the wire. Instead, the browser indicates that it can accept compressed data if the server can send it. The app server then compresses the response, which transforms the 500 kb data to about 20 kb.

Compression is enabled by default on all ServiceNow application servers. The application server always sends compressed data if your browser accepts it. There are browser settings that control whether your browser accepts compressed responses.
