Hi, Bruce

```

<para&gt; Previously <acronym&gt;JIT</acronym&gt; was enabled by default, and activated based on optimizer costs, but this costing has been determined to be unreliable. &nbsp;This this change requires sites that are doing many large analytical queries to manually enable <acronym&gt;JIT</acronym&gt;. </para&gt;```
This this, double "this".
