#7159 closed defect

Layer merging performance — at Version 1

Reported by: Don-vip Owned by: team
Priority: normal Milestone:
Component: Core Version: latest
Keywords: Cc:

Description (last modified by Don-vip)

The "merge layer" action can be slow as hell. With these two data sets, including only new primitives:

  • A: 30.000 highways, 80.000 nodes, 9.000 relations associatedStreet
  • B: 65.000 addr:housenumber

The loading of each data set takes only few seconds. However if I try to merge them, I'm forced to cancel the operation after several minutes of processing without any visual indication of the remaining time.

Two things to do here:

  • Speed up the process, it shouldn't take so long (I have added some traces to measure performances, JOSM merges nodes at the incredible speed of 40 nodes per second !)
  • Indicate in a progress bar the advancement (currently, there is no progress bar at all)
