Description
Please compare the performance of SteamPipe_N in the ScalableTestSuite, between v. 1.13 and v 1.14.
The times spent by matching and sorting are
| N | 1.13 | 1.14 |
| 160 | 0.21 | 6.1 |
| 320 | 0.06 | 21.8 |

We already discussed this issue extensively in #5952, but apparently there is still someting wrong there.
