Introduction

• SPECweb99 is a benchmark developed by the Standard Performance Evaluation Corporation for the purpose of evaluating the performance of World Wide Web servers. The benchmark generates simultaneous static GET, dynamic GET, and POST operations to simulate real-world web server access patterns.

Results

• [15 November 2002].  Current focus is on 8 and 16-way scalability.
• [13 November 2002].  Approximately 3100 simultaneous connections on an 8-way P-III 900 MHz server using Apache 2.0.36. Approximately 640 simultaneous connections UP, for a scaling factor of 4.8. 

Test Environment

• Intel 8 x PIII Xeon w/ 2MB L2 cache, 32 GB RAM, 1 15k RPM SCSI disk. 16 Up client machines.
• 2.5.47 kernel, Apache 2.0.36
• 4 x Intel PRO/1000

Notes: SPEC™ and the benchmark name SPECweb99™ are registered trademarks of the Standard Performance Evaluation Corporation. This benchmarking was performed for research purposes only, and is non-compliant, with the following deviations from the rules:
1.  It was run on hardware that does not meet the SPECavailability-to-the-public criteria.  The machine is an engineering sample.
2.  access_log wasn't kept for full accounting. It was being written, but deleted every 200 seconds.
