"Recent tests conducted by researcher Networkshop Inc. indicate that powerful Web servers capable of handling hundreds of transactions per second may be brought to a near standstill by heavy SSL traffic."

"The growing problem of SSL performance has driven vendors to develop devices that can help share the Web server's processing load. IPivot Inc. next month will ship two new processors that can offload authentication and encryption on e-commerce sites."

"According to Networkshop, even the most powerful, general-purpose Web server hardware can be dragged down by large volumes of SSL traffic. In its most recent tests, the research company found that a typical Pentium server configuration running Linux and Apache, which at full capacity can handle about 322 connections per second of standard HTTP traffic, fell to about 24 connections per second when handling a full load of SSL traffic.

"A similar test conducted on a Sun 450 server running Solaris and Apache experienced even more trouble. The server handled about 500 connections per second of HTTP traffic at full capacity, but only about 3 connections per second when the traffic was secured via SSL."
