The following settings affect performance and security.
HTTP clients can tell the server that they accept compressed data in an HTTP request. Enabling the Apache DEFLATE filter can dramatically reduce the over-the-wire size of metadata such as catalogs and manifests. Metadata such as catalogs and manifests often compress 90%.
Increase the MaxKeepAliveRequests value to allow clients to make a larger number of pipelined requests without closing the connection.
The proxy timeout sets how long Apache waits for the back-end depot to respond. For most operations, 30 seconds is satisfactory. Searches with a very large number of results can take significantly longer. You might want a higher timeout value to accommodate such searches.
Make sure that forward proxying is disabled.
