| 06:05 | <alkisg> I haven't tested nanopi, but rpi4 is still more than 10 time slower than the cheapest PCs around, so I'd say they have a long way to go before they can be used as desktop PC replacements
| |
| 06:13 | wyre is now away: Auto away at Thu Apr 13 06:11:51 2023 UTC | |
| 06:41 | <fiesh> alkisg: it's not unreasonable to assume the nanopi is like 5 times faster than the raspberry though: https://gadgetversus.com/processor/broadcom-bcm2711-vs-rockchip-rk3588/
| |
| 06:41 | but of course one would have to give it an actual try
| |
| 06:43 | <alkisg> There things also usually have GPU issues, e.g. video decoding acceleration isn't easy, so they have issues with watching videos on the browser etc
| |
| 06:43 | I would love to test TV boxes instead; there are some 8-core, 8 GB RAM TV boxes with just 50€ each, gigabit and all...
| |
| 06:44 | wyre is back | |
| 06:44 | <alkisg> But for the average Joe that doesn't want to spend weeks in tuning things, a PC is usually much faster and hassle-free

| 06:57 | <fiesh> the nanopis are also 8 core, 8GB ram, 2.5gbit etc.
| |
| 06:58 | yeah that's true, and having a different architecture is a downside indeed
| |
| 06:58 | for us, it would be almost a show stopper since we'd need to cross-compile constantly, which would be quite annoying

| 17:25 | <Tomahock> Hello, I have installed LTSP on ubuntu server 18.04 based on the official guide, in the initial tests using laptops as clients in three different buildings (between the furthest client and the server there are 3 switches) that are connected by fiber optics and of course inside of each pavilion the connection to the client is by UTP, the performance
| |
| 17:25 | is acceptable, I can navigate, watch videos on youtue, open openoffice, everything works fine, the problem is when I do the tests with the Thin Client HP T5565 which I want to reuse, here It takes me almost 4 minutes to load the desktop and the response is very slow. Mozilla Firefox barely loads and I never managed to watch videos on YouTube
| |
| 17:25 | because the response is very slow.
| |
| 17:25 | This Thin Client HP T5565 has the characteristics:
| |
| 17:25 | Hard disk: 1GB
| |
| 17:25 | RAM: 896MB
| |
| 17:25 | Processor : Via nano U3500@1000MHZ
| |
| 17:25 | With these hardware capabilities that are very limited in sight, is there a version of LTSP and on what version of Ubuntu could I install to be able to use the T5565 thin clients, as it is for a school, the basic needs that clients must have is that they can navigate , watch youtube, be able to edit documents with open office.
| |
| 17:25 | Do I have any possibility or outright those thin clients are already to be discarded.
| |
| 17:26 | <alkisg> Tomahock: see what I wrote yesterday, you'd need an older internet
| |
| 17:26 | Today's Internet needs 4 GB RAM. In any OS, old or new, and any browser, old or new.
| |
| 17:28 | <Tomahock> I understand, so with the hardware capabilities of this thin client there isn't much that can be done?
| |
| 17:29 | <alkisg> You can use local apps such as tuxpaint and view videos using media players like vlc
| |
| 17:29 | You can't browse the web with 1 GB RAM
| |
| 17:30 | Now if it takes 4 minutes to load, that's a different issue, possibly bad networking
| |
| 17:30 | Did you do the lan benchmark test I mentioned yesterday?
| |
| 17:30 | https://epoptes.org/documentation/lan-benchmark/
| |
| 17:42 | <Tomahock> Yes, today I did the tests from the point furthest away from the server, which is 3 switches away, with a laptop, it loads the desktop and the response is acceptable because I watch videos, browse, use openoffice, but when I test it from the thin client from those same network points becomes extremely slow.
| |
| 17:42 | These are the network values
| |
| 17:42 | https://files.fm/u/xyc85z946?ak=ec1e3#/view/5yctte8ed
| |
| 17:51 | <vsuojanen[m]> 1GB RAM is too little. I tested couple years ago the Ubuntu 18.04 and it's not usable for browsing
| |
| 17:51 | <alkisg> You have two issues there; one is that two clients are 100mbps instead of gigabit. But more importantly, there's nothing in the "download" column, which means half of the traffic is blocked
| |
| 17:51 | (assuming you have the latest epoptes version in both the server and the clients)
| |
| 17:56 | <Tomahock> If I did this test from a laptop, it is the furthest point with three switches until I reach the Ubuntu 18 server, with these values the answer was acceptable because I was browsing, watching videos on YouTube, etc.
| |
| 17:56 | This is the version of epoptes
| |
| 17:56 | https://files.fm/u/burwun83g#/view/tus4pepxs
| |
| 17:58 | <alkisg> Anyway even if you fix your networking, you won't go far with 1 GB RAM. It's just for local apps like tuxpaint and vlc; you can't browse the web with them
| |
| 17:59 | For the best result, use ubuntu mate 18.04 32bit, and format the 1 GB local disk of these clients as swap partitions
| |
| 17:59 | But again, even with that, browsing won't work
