| 1 | The purpose of this benchmark is to compare the performance for |
| 2 | userspace tracing of SystemTap and LTTng-UST. |
| 3 | 10 million events generated per thread, number of threads vary. Each |
| 4 | event generates a time-stamp and contains a 4-byte integer value. |
| 5 | |
| 6 | These four tests can be performed : |
| 7 | - UST in flight recorder mode |
| 8 | - UST writing the trace to disk |
| 9 | - SystemTap in flight recorder mode |
| 10 | - SystemTap writing the trace to disk |

| 12 | Dependencies |
| 13 | - LTTng-UST (tested on v0.11) : git://git.lttng.org/ust.git |
| 14 | - SystemTap (tested on v1.2-5 from debian packages) |
| 15 | - systemtap-sdt-dev for dtrace |
