You are providing very little information which makes it difficult to
help. For starters:

* What firmware version?

* What version of ath10k are you using?

* Are you sure that the host is not limiting the throughput in any way?
  Try to disable _all_ kernel debug options.

* Also describe your test setup in detail.
