The cache alignment happens because it hits a specific size threshold, and
jemalloc/phkmalloc(I think!) just round everything up to be page size
aligned.
The underlying problem may actually be a code change to how the math is
done. It just runs slower on page-aligned alignments..

It all boiled down to how jemalloc versus the linux allocator(s) allocate
blocks. jemalloc will page align things after a certain size. Linux didn't.
So when doing numeric processing,
