General Results
- MySQL 5.5 and 5.6 both performed significantly better than MySQL 5.1.
- Read/Write and Read Only workloads testing requests per second show a marked improvement for both MySQL 5.5 and 5.6 over MySQL 5.1.
- The 95th percentile response times (explained below) for both Read/Write and Read Only workloads on MySQL 5.5 and 5.6 were much lower (thus faster) than MySQL 5.1.

- 8 GB of RAM
- 2 x Crucial M500 240 GB Drives
- RAID 1, using an LSI 9260-4I RAID Card
Constants
- Physical Server Hardware

Test Descriptions
- All testing was done with Sysbench.
- MySQL and Sysbench were running on the same host, meaning that both were communicating via Localhost.
- “Warm-up” tests were conducted before recording results.
- Requests per Second: The total number of requests the MySQL server was able to respond to per second.
- 95th Percentile: The number, in milliseconds (ms), below which 95% of the response times fell.
- Read/Write Workloads: MySQL performs Selects, Deletes, Updates, and Inserts.
- Read Only Workloads: MySQL performs Selects only.
