High PHP-FPM Memory Usage After Switching from Zeta to Eta Theme

Hello,

I recently switched my Osclass website from the Zeta theme to the Eta theme, and since then I've noticed a significant increase in PHP-FPM processes and memory usage.

My server is a 6 GB Contabo VPS running PHP 8.3 with MariaDB.

Here is what I've observed:

Before switching to Eta, the server memory usage was noticeably lower.
After enabling Eta, PHP-FPM keeps around 29 worker processes running, each using approximately 100–110 MB of RAM.
MariaDB uses around 600 MB, which seems normal.
There is almost no real visitor traffic on the website.
The PHP-FPM pools are configured with pm = dynamic and pm.max_children = 16, but this configuration has not changed—only the theme has.

I also receive a lot of spam submissions through the contact form, but I'm not sure whether this is related to the Eta theme or just a coincidence.

Has anyone experienced higher PHP memory usage after switching to the Eta theme?

Are there any known issues, recommended settings, or specific Eta features that could keep PHP-FPM workers active or increase memory consumption?

Thank you in advance for any suggestions.

Theme may consume more memory as it has more db calls then default Sigma, but it should have only minimum impact on overall resources.

Osclass behaves nicely, doesn't take up too many resources. Also, the Eta theme is not more demanding than, say, Zeta or Epsilon.

Try installing "btop" on your VPS and use it to find in real time what could be causing a higher resource requirement.

I am also using Eta theme since last 7 days.

Let me just add that the site processes over 10,000 ads, the database is 300 MB, and this is the current state. No lies, no deception. I am very satisfied. What do you think about whether it's ok?

I really like the new theme too - great work!

I've also switched from the Zeta theme, the resource usage on the database is significantly higher with the new theme.

I've got APCu installed for my cache which really helped lowering the load for non logged in users on the Zeta theme, it doesn't seem to help much when I enable the APCu cache on the new theme though.

Thanks again for the new theme - your work is much appreciated!
