Why does osm make multiple db calls to get the same resource?

I have a private osm server and i have a problem with it's performance. I noticed that the server make multiple requests to the db when potlatch is waiting (loading data). I believe these requests are from different threads because the timing is very similar.

1	Your question is actually about how Ruby on Rails works, rather than anything to do with OSM specifically. If you'd like to know how Rails works there's plenty of information available. permanent link answered 14 Nov '11, 17:20 Jonathan Ben... 8.3k●17●85●108 accept rate: 18%
