Siege Benchmark Test #1: Benchmark mode
Centmin Mod Nginx auto installer includes an option to auto install Siege. This test ran from a separate 4th VPS in Chicago, IL against 3x 512MB / 1GB Burst OpenVZ VPSes load balanced via HAProxy.
Note: A 256 concurrency level with 1 second delay (-c256 -d1) translates to roughly 47,000 unique visitors per day.
