nice work regarding the vert tables! was also starting to suspect it was increasing io. i went down a different route with my benching and tried to understand the ultrafast internals a bit better. i came up with a few patches ive been running that have shown measurable improvements. namely, i want to move anything that can be considered sig verification to the GPU, i.e., no CPU marshalling batches and instead columns are streamed directly into reusable GPU buffers, verified on device, and copied back. i dont think we can ever truly get zero copy since we have to cross a device memory boundary. but if that is possible and the goal, i think this at least is a good step toward it anyways. @Vano Chkheidze you can see the patches i am using here: github.com/josibake/…/patches
