SPECweb99_SSL Benchmark (Retired: October 2005)

SPECweb99_SSL answers the need for a meaningful measure of the web server load generated by servicing encrypted requests, which have become more prevalent on the web over the last few years. SPECweb99_SSL adopts an industry-accepted workload to measure the performance capabilities of a web server with added SSL encryption/decryption.

SPECweb99_SSL is built on the same test harness and uses the same workload and filesets as SPECweb99. It tests secure web server performance using HTTP 1.0/1.1 over the SSL Protocol. It is an extension of, rather than a replacement for, SPECweb99.

Code Defect Identified in the Windows port of the SPECweb99_SSL test harness
07/22/2003 - SPEC has identified problems with the port of the SPECweb99_SSL test harness to the MS Windows operating system. The code defects prevent the client systems from generating the correct SPECweb99_SSL workload. It should be noted that the problems are solely within the the port of the SPECweb99_SSL code base to the Windows OS and not due to either the Windows OS or the OpenSSL library. Details are available in the full notice.

New: Alternate version of 'manager' available (05/29/2003)
An alternate version of 'manager' is available to current benchmark licensees; this version allows you to retrieve the POST log from the SUT faster by bypassing the web server and doing a direct network copy using rcp (or an equivalent for your OS). To request a copy of the alternate version of manager please send an email, along with your license information, to
