| 3 | We tested the speed of the extractors by running them on a Intel\ Pentium\ 4 CPU,
|
|---|
| 4 | 2.4\,GHz machine at Barcelona and measured
|
|---|
| 5 | the number of events executed per seconds. The results differed by about 20\% from one try to another (on the
|
|---|
| 6 | same extractor), but in general, the differences between the extractors are much bigger than the intrinsic fluctuation.
|
|---|
| 7 | Table~\ref{tab:cpu} shows the obtained results.
