Hello,
Does dm-crypt support multithreading. Have found sites stating yes, but the configuration is unclear. Contacted Redhat, they linked to a 6-yr old post saying no despite the newer posts.
Thank you for your assistance.

Yes (if the question is if dm-crypt uses all cores while enrypting IOs).
For RHEL it depends: for RHEL6 there is only parallel processing if it is submitted
from different processes, for RHEL7 it is the same as upstream (dm-crypt
uses all cores).
What 6-year old post you mean? (If it is RHEL6, then it is perhaps correct.)
