[2023-11-17 00:22:55] <armagetronbridge> 10irc:Lucifer_arma| I was actually thinking things like "I don't use bluetooth on these things, so I don't need the bluetooth service", and from there, what other services do I really not need?

[2023-11-17 00:24:06] <Lucifer_arma> but then you get into the weeds pretty quickly.  I need a network service, but which ones do I really need?  right now, all the nodes are connecting through wifi, so I need some sort of wifi service, but the one provided is aimed at desktop users that might be wondering from one network to another

[2023-11-17 00:26:02] <Lucifer_arma> how much HAL do I need?  It's not like the hardware changes, and I'm not hotplugging usb drives or anything.  I could disable usb completely, except it's a raspberry pi and everything goes through usb internally

[2023-11-17 00:26:52] <Lucifer_arma> I'm actually thinking it would be easier to build a custom distribution from scratch for my needs than it would be to pare one down, but I"m not opening that can of worms yet

[2023-11-17 00:27:41] <Lucifer_arma> especially when I can improve performance by 33% right now for only about $80

[2023-11-17 00:28:27] <Lucifer_arma> hm.  How big does a cluster have to be before it becomes more cost effective to increase performance through software improvements rather than throwing more hardware at it?

[2023-11-17 04:40:34] <armagetron-bridge> 12discord:zman_0| @northernscrub I'm using Manjaro since basically forever, generally happy with it. The AUR stuff is hit and miss, though. Quite often, it simply does not work, or requires tweaking. If not native package is available, which obviously is best, I tend to first look for a Flatpak. Once you have all the basic frameworks installed, the incremental storage bloat is not so bad 🙂

[2023-11-17 08:33:22] <armagetron-bridge> 08discord:delinquent| Lucifer_arma aye, for that I'd look in /proc/<pid>/cwd. That will tell you what the working directory of the thread is, which should give you an indication of what it does.

[2023-11-17 08:38:51] <armagetron-bridge> 08discord:delinquent| As for software vs hardware optimisation, there's no clear answer there. Back when I worked at HP, our array had two component systems, one being a stack of RHEL machines and one being a stack of HP-UX (think AIX but with HP branding) machines. All of those machines were running stripped-down systems that ran the bare essentials, but I don't think we went as far as getting rid of <clipped message>

[2023-11-17 08:38:52] <armagetron-bridge> 08discord:delinquent|  every little thing. We were more focused on running without unnecessary software packages - so no java, no apache(duh), no extra shells. If BT stuff was provided by Bluez, I suspect that was stripped from the image too. However, getting rid of device monitoring was probably far beyond the scope of necessary

[2023-11-17 09:05:47] <armagetron-bridge> 13discord:Juesto| may i recommend chaotic-aur aka chaotic-cx? it compiles the most popular aur packages so it gets you covered for computers that are not designed to be build workhorses because of thermals or slowdowns

[2023-11-17 09:11:11] <Lucifer_arma> It also depends on what your hardware is doing.  A webserver that spends a lot of time idling isn't going to benefit at all from being stripped down (outside of normal security concerns, of course)

[2023-11-17 09:11:33] <Lucifer_arma> and for a webserver, idling is a good thing, because it means your site is fast and responsive to users

[2023-11-17 09:12:25] <Lucifer_arma> but for a HPC, where you're running every core at 100%, then those little processes start to add up

[2023-11-17 09:13:28] <Lucifer_arma> again, on one node, or a few nodes, they don't matter.  But at some point, say 100 nodes, then if you remove a service that just monitors USB for anything getting plugged in, you can recover the equivalent of a couple of nodes' worth of performance by removing the service from all of them

[2023-11-17 09:15:02] <Lucifer_arma> but without knowing what every service does, I don't even have a starting point for figuring out how much CPU time is being wasted on unnecessary services

[2023-11-17 09:15:48] <Lucifer_arma> I guess I'll poke around some later.  I'm not really at a point where it matters, and honestly, I think building up from scratch is a better option anyway.  Ubuntu offers a way to do that, so I don't have to go completely from scratch

[2023-11-17 20:33:30] <Lucifer_arma> wow, my database is soooo overloaded right now.  I *really* need to do some performance improvements to it.  Here I was thinking I might get another raspi, but not if the database is struggling with three nodes already
