This makes sense to me, but I'm a little confused about how you described the test condition: > baseline: main branch where we unset RAMBufferSizeMB, which defaults to 16Mb with force merge at the end of indexing. I'm not sure what unset means? I guess it goes to the default 16MB, but I assume you must be doing the same in the other test condition? Is there some difference in how the IndexWriter is configured between the two conditions? Or maybe I'm misunderstanding and you are allowing the entire set of vectors to buffer in RAM (in the baseline case)? But if that's the case the results are truly astounding! Actually I would like to understand the difference between that case, and buffering on disk. Do we pay any penalty for buffering on disk? how much? -- This is an automated message from the Apache Git Service.
