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 | |
