• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Optimize spare RAM

New Pleskian
12.5 running at DigitalOcean on the 4CPU/8GB plan Ubuntu 14.04. I originally upgraded to this one from the 4GB plan because I needed additional storage space but not so much anymore. I'm hosting about 10 WordPress sites using FPM through Apache for PHP processing. Sites range from 500-25K visitors per day.

I hover around 6GB free of RAM at any one time and I'm looking to utilize this better because it seems like such a waste just sitting idle. There's tons of threads on people running out of memory but in this case my cup runneth over.

What are some things I can do to get more bang out of this extra RAM that is never in use?
