Sébastien DeleuzeIf you are using #R2DBC, I strongly recommend upgrading to Spring Boot 3.3.5 which contains an amazing optimization crafted by Mark Paluch and Dariusz Jędrzejczyk which provides a huge performance boost (higher throughput, lower latency) under high concurency. https://spring.io/blog/2024/10/24/spring-boot-3-3-5-available-now
Notice that for now, only Postgres takes advantage of this optimization (see https://github.com/pgjdbc/r2dbc-postgresql/issues/668), other database drivers will need to be updated as well for similar benefits.
Ben Hale@sdeleuze incredible that the change was that small.
@nebhale Indeed! See the result on my local machine, the gain on latency is impressive. https://github.com/TechEmpower/FrameworkBenchmarks/pull/9341

Hey, I am Sébastien the Spring Framework committer. This simple PR that updates to the latest R2DBC version should improve some DB tests very significantly under high load thanks to some optimizati...
@sdeleuze this was always in my mind as we worked on Reactor/R2DBC: we knew the amazing performance of non-blocking on a single thread by watching Node. But we got to use multiple threads so it should be insane. This just proves it again.
