System, Method and Computer Program Product to Maximize Server Throughput While Avoiding Server Overload by Controlling the Rate of Establishing Server-Side Network Connections
First Claim
1. A method for improving performance of a server by device intermediary to a plurality of clients and the server, the method comprising:
- (a) monitoring, by a device intermediary to a plurality of clients and a server, a mix of requests from existing clients and new clients pending at the server;
(b) determining, by the device responsive to monitoring, for the server to perform within a predetermined performance range, a first predetermined percentage of processing resources of the server to service existing clients; and
(c) regulating, by the device, a rate at which requests received by existing clients are delivered to the server to maintain performance of the server within the predetermined performance range.

Abstract
A method for maximizing server throughput while avoiding overload of a server is presented. The method involves intercepting, via an interface unit, a client request for information from the server. Next, the interface unit determines the current server performance, where the server performance is based on the number of connections opened to the server, the response time of the server and the rate at which the response time is changing. Finally, the interface unit forwards the client request to the server if the current server performance is close to an optimal performance, whereby avoiding overload of the server.
