Disclaimer: I didn’t find a solution, but I did find some crazy code. The fact that this shows up as CPU time suggests that the reads were all hitting in the system cache and the CPU time was the kernel overhead (note ntoskrnl.exe on the first sampled call stack) of grabbing data from the cache. Think about that for a moment.

The solution used in Scrapbook was to use the SWR library of React hooks to update the cached page from the server with client side data fetching. The client is first served the cached statically generated page (generated with getStaticProps() ), in the background the server also begins the process of revalidating that page (read more here ).

Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged.
