Question Overly large memory usage

[freyfrey01]

Hello, I'm starting to be a system admin for a beefed-up windows server and lately have noticed a large amount of memory usage.
Background info-

OS: Microsoft Windows Server 2022 Standard v. 10.0.20348 Buitld 20348
RAM: 144 GB
CPU: 36 total cores spread apart 36 single-core Intel Xeon Platinum 8268 CPUs
(I do not get to change or manage the hardware)
This server is running a web application, several standalone scripts, and a PostgreSQL 16 database.

I've noticed the memory usage continues to go up throughout the week and can only be fixed from getting to high by rebooting the machine which brings the usage back to normal levels.

I've become slightly more familiar with VMMAP, RMMAP, and Process Explorer (screenshots below). My major concern and where I feel my memory is being soaked up is in the screenshot of RMMAP which shows 65,013,548 KB as "Active" within the "Unused" usage.

Any assistance finding where this memory is going would be great.

You need to talk to your developers and see what their code is doing, and how it can maybe be optimized.
Database admin, front end, etc, etc.

This is not something we out here can diagnose.

What tuning have you done on your "web application" ? -- https://stackify.com/w3wp-exe-iis-worker-process/
Most applications can be tuned to lower the memory requirements. That might mean tuning the Java JRE other environmental applications.
