I'm unable to share the indexing schema, I'm under strict rules on exposing anything project specific.
I've been using a tmpfs memory mounted file system for the slapindex
slcToolThreads I've experimented with a bunch of settings, from 4-48 with 16 physical cores, but no matter what I do it only ever pins one core to 100%.
It looks like the documentation needs updating. For back-mdb, any value above 2 is set to 2, as it has no improvement in indexing performance.
A better question would be, is why are you running slapindex at all? Generally one loads their database with slapadd, which includes indexing the database. If you need to change the indexing for a specific attribute, then you slapindex *just that attribute*.
If you are doing slapadd followed by slapindex you're wasting resources, assuming your indexing hasn't changed.
It's unfortunate you cannot share your indexing since it's possible that there unnecessary indexing involved.
