I've just stumbled upon this undocumented compiler option which we apply unconditionally, and found https://devblogs.microsoft.com/cppblog/visual-studio-2017-throughput-improvements-and-advice/#compiler-back-end (section "Inline Reader Cache"). So using that cache might improve build time, but may yield worse optimization (https://devblogs.microsoft.com/cppblog/inlining-decisions-in-visual-studio/#we-inline-pre-optimized-code). It might be a good idea to revise the usage (especially N=1).
