With Loom, the simple, blocking, non-reactive frameworks (like Spring MVC) should give you similar throughput to the reactive ones -- that's the main impact. I don't know how reactive frameworks intend to make use of Loom.
Loom will be a performance game changer even for reactive frameworks. I'm not even talking about it the fact it use io_uring and other SOTA OS technologies.
I'm talking about the fact it allows to have a non blocking socket thus enabling for the first time asynchronous jdbc access and thus postrgresql pipelineing/batching.
This will allow spring to come at the top 4 fastest http servers on earth according to the benchmarckgame
