Therefore, a very small request. Would it be possible on your side to run the same
experiment as with (BIND 9.16.32 / BIND 9.18.6 / BIND 9.19.4) one more time but
with BIND 9.16.21 (or any other version in 9.16.x <25 range )?
Why not the opposite

Dmitri,
Just downloading, building and installing the latest version of jemalloc
like this doesn't mean that BIND will find and use it. BIND has to be
compiled with the correct compiler and linker flags to use this version.
Are you certain BIND is using your installed version?

I don’t see jemalloc anywhere in your setup scripts. Preferably use the latest

I would need the exact algorithm how did you generate the zones.

We will test with a higher kernel.

I don’t want to delve into vague description of your experiment. You’ll have to
share the exact scripts.

Please read the whole thread on measuring the real consumed memory.
The '“top” RES value' has little or no value at all.

There’s no generic tool. The one that was mentioned in the article was tailored

In any case, the article is only tangential to the topic here. It talks about a

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
46 matches
