Re: jessie sub-100MB RAM at boot

"Reduce Debian" is interesting, but some of the information might be out of date. eg none of the packages linked to in the "cups" section exist any more.

Of course, you go by the graph, so 130 minus some for lxtask itself, or conky, or the terminal you run htop in, or however you monitor such things.

The rest of what you wrote is neither here nor there (in this case the processes are being started in ~/.config/autostart and ~/.config/openbox/autostart. xfce4-screen-shooter is there because I'm taking a screenshot and lxtask because I'm monitoring tasks *cough*).

I edited the thread title, it seemed unnecessarily flame-baitey.

Cut down the processes, cut down the RAM usage at boot.

My nearly 5 year old i3, 3GB RAM boots up at 38MB without Xorg and all, 87MB only with Polkit stuff, Tint2 and Thunar and at 164MB with all processes on. I am not that worried about how much RAM used at boot, as I have 3GB RAM.

Re: jessie sub-100MB RAM at boot

But after an hour of uptime, jessie's using over 155MB at idle anyway and there's no loss in performance, that's my point

*Jealous of hhh, how dare you Sir complain of 155mbs ! For real your stats sound pretty dang good for modern nix.

Yeah, I still focus more on sys resource usage than is probably healthy and/or productive. Not the insane resource fanatic from dys gone by anymore though.

Guessing neither are many of the opensource devs of the world. Outside of special purpose projects, devs or maintainers who are devoted to older systems-etc. Don't think the gnu/nix devs of the world put nearly so much focus on it anymore, with RAM being so plentiful in so many systems.

Jmo .. makes much sense, IF they're taking advantage of it for actual productive purposes. ie: Increases speed/performace/stability/security, allows additional features etc blahblah.

Would be negligent on their part if they didn't use the availability of more resources to enhance their projects and performance. Things have clearly changed in terms of avg system resources and they'll change accordingly to utilize that fact.

Like all things nixish, many of those things in how the kernel or OS-distro uses and manages available memory can be config'ed to better suit x-nixers personal preferences.

Still am a 110% committed efficiency fanatic. aka: Tweakster, always something to focus optimization efforts on. Memory usage will always be one of those for me too.

With gnu/Linux you'll never have a shortage of things to optimize or tweak the hell-outta. Lol ... what you probably will have a shortage of, time to devote to tweakage efforts. DAMMIT !

A little less for my Xfce4 setup. So, yeah, first world problems.

@hhh -- does BL use less memory if you start it with sysvinit rather than systemd?

Re: jessie sub-100MB RAM at boot

Lmao hhh ...

You're doing a bit better than me fellow nixer. Think this OS boots at almost 180mbs. Haven't really gotten obsessive about tweaking the thing yet outside of a applying the norm.

Jmo .. looks like you're doing really well in terms of system overhead though. smile


Vll!
