<p class="MsoNormal">Hi ISC, <br>
<br>
We have run an experiment with:<br>
<br>
1. one zone<br>
2. basic configuration <br>
3. ~100 MIL of A(2/3 of all records) + CNAME(1/3 of all records) records in the zone file. Other types not tested.<br>
<br>
RAM consumption (as monitored from "top" RES value) in RHEL 7.9 was 2 GB higher in 9.18.5 (with Jemalloc 5.3.0) vs 9.16.21 (w/o Jemalloc).
<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal"><br>
Here is the key question: Should the memory reduction apply to our experiment? Please let us know if any additional details about our experiment are required.<br>
<br>
If not, could you please add additional details about the memory reduction statement and scenarios it applies to?
<br>
<br>
Best regards, <o:p></o:p></p>

I'm eager to see reproducer for this +10 % increase but so far it was<br>
not verified.<br>
<br>
I did lots of testing and simply cannot reproduce it, so it might be not<br>
surprising I consider it a bad idea to extend our articles with<br>
information we cannot verify.<br>
