| + | ===== Desired Benchmark Features ===== | ||
| + | |||
| + | ==== For command-line apps applications ==== | ||
| + | * Run-time | ||
| + | * Memory usage | ||
| + | * Hardware performance counters (if available), using PAPI | ||
| + | * Simulated hardware statistics, using cachegrind | ||
| + | * These should be combined into a single representative number, using some hardware model. | ||
| + | * Ability to compare all of these over two runs | ||
| + | * Support for other PHP implementations | ||
| + | * Benchmark characterisation: | ||
| + | * This is hard to do properly, so best to do it badly and give coarse grained information. | ||
| + | |||
| + | *TODO* | ||
| + | |||
| + | ==== For web-apps ==== | ||
| + | |||
| + | * Requests per second | ||
| + | * Memory usage | ||
| + | * Bottleneck (is it scripting, DB, or network) | ||
| + | * Total time for request | ||
