Thanks! The caption of Figure 1 lists the page size used by each system (i.e., the default configuration). We use different page sizes across systems, and as you said, it is a bit difficult to compare them directly apples-to-apples. This is actually intentional! Because this also exposes the B-tree index-level write amplification effects. In that sense, Figure 1 kind of suggests that larger page sizes may not necessarily be great for write amplification. And yes, you are correct regarding Postgres. Instead of having a separate doublewrite buffer file, Postgres relies on WAL full-page writes…

Hi, I’m the first author of the paper. Thanks for the interest and the kind comments. The extended version is available on arXiv if you’d like more details: https://arxiv.org/pdf/2603.09927 The appendix includes additional details and FAQ-style answers that did not fit into the VLDB version.
