Ok I understand better. Solr does not "read" the 1 to 900 docs to retrieve 901 to 1000 but it still needs to compute some stuff (docset intersection or something like that, right?) and sort, which is costly, and then "read" the docs.

The 10 requests are simultaneous which is I think an explanation of the issues we encounter. If they were consecutive, I'd expect to take benefit of the cache indeed. > What are you trying to accomplish when you make these queries?

It's not a behavior we are deliberately doing or encouraging. But before discussing with them, we wanted to understand a bit better what in Solr explain those response times. Regards, Gaël
