Hi!

We noticed a significant slowdown in our production service after upgrading from 0.2.x to 1.x. After profiling, we determined that the culprit was the check_alignment() function, which wasn’t inlined, despite being very small, and was taking up a lot of time. Marking this function as #[inline] fixed the problem.

Unfortunately, I didn’t find a way to replicate this regression in a benchmark, but inlining such a small function is unlikely to cause performance problems and was significantly beneficial in our case.
