Systems and methods for performing localized server-side monitoring in a content delivery network

A computer-implemented method for optimizing content delivery, the computer-implemented method comprising:

• monitoring a first throughput rate with which outgoing application layer packets of first content pass from a particular server to a first user;
• determining content delivery performance to the first user based on said monitoring;
• receiving a request for second content at the particular server from a different second user;
• and
• optimizing transfer of the second content from the particular server to the second user before passing a first packet of the second content to the second user and in response to the content delivery performance to the first user, wherein said optimizing comprises at least one of (i) configuring a second throughput rate with which to initiate passing the second content to the second user based on the first throughput rate of the first content to the first user or (ii) selecting a particular encoding from a plurality of second content encodings to pass to the second user based on the first throughput rate of the first content to the first user, and wherein said optimizing further comprises reducing resources consumed in transferring the second content to the second user in response to the content delivery performance to the first user not providing a specific user experience.
