It's been like 5 years since CentOS 7 was released.
Ubuntu 18.04 LTS servers uses 90 MB out of the box

Any idea what 19.10 does? But yes, Ubuntu has remained lighter than CentOS and Fedora, which is one of its biggest benefits.

You'd think they'd have had more time to make it leaner!

Debian latest is even better than Ubuntu, surprised to see this I think centos 8 is still not really ready tbh. Even no minimal images to download, you need to download 4gb image.

interesting, i am using VMware workstation at work. will update all pkgs and reboot and see

Same thing actually weird, maybe KVM is better at RAM cause it shares the RAM or compresses it , I heard about this feature, it would be interesting if this it.
wait a second your running 25 tasks and i am running 30 ? what gives. I am running minimal install . oh maybe it detected vmware stuff and installed vmtools and agents and that is causing . yup i remeber now it installed those agents
do disabled vmtoolsd and rebooted same thing, it seems it is what it is

I made this post a couple of moths ago and it's the same as what you are seeing.
@Pete-S said in Are Minimal installs really better?:
If we are talking Fedora Minimal Install then it's actually a pretty bloated affair compared to others like Debian for instance (only the base system, no extras). Even Fedora Custom Operating System option, which I assume is smaller than minimal, is bloated in comparison.
I have both installed on my test host in the latest versions and looking at dmesg Debian boots in 2.7 secs compared to Fedora's minimal/custom 9.7 secs. After boot Debian uses ~80MB RAM while Fedora uses ~240MB RAM. Fedora of course has more services running by default and pulls in more packages during install. Even Fedora Server's netinstall disk image is about twice the size.

Interesting, thanks. sorry i missed that.
Debian rocks, also JeOS, i think that also is great for KVM guests, especially limited RAM ones.

Totally agree with you about Debian.
This is Debian 10 with everything unselected during the install on KVM

They are focused in playing catch-up, not on improving the system itself.
