Hello,

I added 4 registration dedicated database workers and removed from registration all accesses to the store. Now the evaluation returns objects that contain all required information. This seem to improve the situation quite a lot. For example, those three registrations were done simultaneously in ~200 seconds: --8<---------------cut here---------------start------------->8--- 2020-10-04T12:46:19 registration took 205.429772 seconds 2020-10-04T12:46:19 evaluation 17099 registered 156 new derivations 2020-10-04T12:46:19 building 156 derivations in batches of 200 2020-10-04T12:46:19 building batch of 200 derivations (0/156) 2020-10-04T12:46:19 registration took 212.892482 seconds 2020-10-04T12:46:19 evaluation 17105 registered 164 new derivations 2020-10-04T12:46:19 building 164 derivations in batches of 200 2020-10-04T12:46:19 building batch of 200 derivations (0/164) 2020-10-04T12:46:19 registration took 205.009416 seconds 2020-10-04T12:46:19 evaluation 17102 registered 160 new derivations 2020-10-04T12:46:19 building 160 derivations in batches of 200 2020-10-04T12:46:19 building batch of 200 derivations (0/160) --8<---------------cut here---------------end--------------->8--- Thanks, Mathieu
