/tp command slows down the server substantially

A couple hundred /tp commands on a couple dozen entities brings the bedrock server to its knees.

How to reproduce

1. Download and open the attached world
2. Power the left command block, then switch to the right one (left does /tp, right does /execute if entity)
3. Observe the repeaters

Expected behavior
Identical (fast) performance for both commands

Observed behavior
/tp is extremely slow
