I've noticed a slowdown in indexing speed going from esv 2.3 to 5.5.0.
It's early days, I have no precise figures and there are a tonne of other things that may differ, but my first thought was that it may be a change I made to doc_values- there are more doc_values now. I presume this will slow indexing speed, but I wonder by how much. I'm seeing a doubling of the time at least to index my corpus of text. Any suggestions ?
