Hi Klarstein,
Gathering the output of named statschannel should be good enough for initial
assessment (json please).
For 9.18, make sure the jemalloc is being used at runtime.
Here are commands you asked for:
1. when running ./configure, make sure the output at the end has this:
Configuration summary:
-------------------------------------------------------------------------------
Optional features enabled:
Memory allocator: jemalloc
2. Then, configure statistics channel in named.conf like this:
statistics-channels {
inet 127.0.0.1 port 8080;
};
3. With that in place you can grab stats from this URL:
http://127.0.0.1:8080/json/v1
Configuration for v9.16 is the same, just skip the jemalloc part.
4. Bonus points for grabbing /proc/<PID>/statm content at the same time
as content of the JSON stats endpoint (if you are on Linux).
I hope it helps.

Can you please provide some commands whose output you are interested? I want
to collect the statistics for 9.16 before updating to 9.18.
Thanks

I would be very interested in hearing more!
In majority of our internal testing 9.16 has higher memory consumption
than 9.18, especially when 9.18 is compiled with libjemalloc. And the
differences are not small, for some configurations it can be even 2x or
3x more on 9.16 than it is on 9.18.
If you encounter it again please get back to us so we can diagnose it.
Thank you!

I remember we had similar issues with 9.18 (isc ppa packages) and hence
wen't back to 9.16. But I can not remember the details.

You did not provided any details, so we can’t really help you.
What is “RAM consumption” anyway? VSZ, RSS, numbers pulled from
stats
channel from named?
What’s the hardware, what is the configuration, how was BIND 9 compiled
(or packaged)?
The more details, the better

Hello Team,
While upgrading from BIND 9.16.10 to 9.18.2, we have observed high
memory consumption.
On version 9.16.2, RAM consumption was 3.8 GB. And on 9.18.2, RAM
consumption is 4.5 GB. Due to this an increase of approximately 20 %
memory is observed.
Is this the expected behaviour or any tuning is needed?
Thanks in advance.
Regards,
Raman
