Hi, so do you think the database connection is the bottleneck? I would need some pointer on where to optimize or at least how to find the bottleneck (or how can I do some profiling/benchmarking/debugging to find the bottleneck?)
Or is it just normal that an ECQL-Filter on many IDs is very slow? Best, Jens Von: Nachtigall, Jens (init) [mailto:[email protected]] Gesendet: Freitag, 31.

The filter is like this: IN ('mylayer.101453', ...up to 5000 IDs here... ,'mylayer.102486') If there are only a few hundred IDs the response is at about 500ms, but with up to 5000 it becomes 15-30 seconds. Any ideas on how to optimize? 2, 3 seconds would sound acceptable but half a minute is a bit too much. What is the datastore backing the request?
