What’s the first sign that tells you a server setup isn’t as stable as it looks?
Lately I’ve been noticing that server performance can feel completely different even when the specs look similar on paper.
I had two systems recently with almost the same RAM and CPU allocation, but one felt smooth all day while the other randomly slowed down during certain hours.
Made me curious how people here usually evaluate a server after deployment.
Do you mostly pay attention to:
- consistency over time
- disk responsiveness
- network latency
- virtualization type
- overall stability
Or do you just know pretty quickly when something “feels off”?
Interested to hear what experienced people usually look for first.
