Description

we switched from Katello 3.9 to 3.16.
Here we have a PUMA webserver with 2 workers and 0to 16 thread.

But with the same infrastructure and load, our Memory utilization spiked to 40% from 20%

Does PUMA require more Memory?

Hi prem prakash,

Since we do not know the hardware specs of your Katello server, could you please let us know what those are? Also, please take a look at the tuning profile information at the bottom of this page to ensure your server meets the recommended specs: https://theforeman.org/plugins/katello/nightly/installation/index.html

Foreman server has 16CPUs and 64GB RAM
Foreman Tuning = Large
Then changed the following PUMA settings:
Environment=FOREMAN_PUMA_THREADS_MIN=8
Environment=FOREMAN_PUMA_THREADS_MAX=32
Environment=FOREMAN_PUMA_WORKERS=8

Hi Prem Prekesh,

Do you see a particular process using a lot of memory? What is leading you to believe the puma webserver change is what is using up the most memory? Could you provide the output from 'top -o %MEM' This would help us narrow down the concern, pulp 3 services were added in 3.15 and could be affecting resources as well. The output of `systemctl status pulpcore*` would be helpful too.
