| 03:38 | <alkisg> mcgwrath: whatever you configure in your server, if you run `ltsp image /`, should appear the same way on the clients as well
| |
| 03:39 | Note that if you add or remove users, you need to also run ltsp initrd, and reboot the clients

| 17:11 | <Tomahock> Hello, I was testing ltsp on ubuntu 18.04 x64, the clients are HP t5565 thin clients that had 1 GB of RAM, I increased it to 4 GB of RAM, there is a slight improvement in the response but it is still noticeably slow, it is possible that I can improve performance if I install LTSP on Ubuntu 17 / Ubuntu 16 in 64-bit or 32-bit version, would there be
| |
| 17:11 | any improvement?
| |
| 17:11 | This HP T5565 Thin Client has the characteristics:
| |
| 17:11 | Hard disk: 1GB
| |
| 17:11 | RAM: 4GB
| |
| 17:11 | Processor : Via nano U3500@1000MHZ
| |
| 17:11 | The moment I open a mozilla window the CPU usage continuously shoots up to 100%
| |
| 17:11 | https://files.fm/u/svehx38dr#/view/jw6nc2pfp
| |
| 17:12 | <alkisg> Tomahock: buy an ssd usb disk. Plug it into that client. See how fast it goes. LTSP will go up to that fast, it won't go magically faster.
| |
| 17:12 | *and install the OS you want in that ssd
| |
| 17:13 | The clients you mention have a cpubenchmark score of 187. That's about 50 to 100 times slower than current CPUs
| |
| 17:13 | It's time to retire them, not upgrade them :)
| |
| 17:17 | <Tomahock> Ok, so for the stated hardware capabilities of the HP T5565 thinclient even though I increase the RAM to 4 GB there isn't much you can do to improve performance, so downgrade from ubuntu to 16 or 17 or install the 32-bit version ?
| |
| 17:17 | Sorry to insist on that topic, it's the client hardware I have on hand :-)
| |
| 17:26 | <vsuojanen[m]> it's just surf through all potential Linux distros and boot their live USB or just get the new hardware
| |
| 17:26 | <alkisg> Tomahock: how many such clients do you have?
| |
| 17:29 | <Tomahock> I have approximately 60, but I want to put about 30 clients into service, I opened Thinclint and it only has one RAM slot in which I put the 4GB module
| |
| 17:30 | <alkisg> If you're going to install 4 GB RAM on them, I would do this test: add an SSD, install Ubuntu MATE 22.04 locally, and see if I like the result
| |
| 17:31 | If a local OS runs fast enough for you, then LTSP can match that performance
| |
| 17:31 | If a local OS doesn't run fast enough for you, throw away the clients, there's no magic that will give you more CPU power without changing the CPU. Even an older Ubuntu won't run today's Internet faster.
| |
| 17:33 | <Tomahock> I understand, the hardware capabilities of the thinclient are very limited, so the only thing left for me to try is what you suggest and if it doesn't work, to the crematorium all the thinclients
| |
| 17:34 | <alkisg> 👍️
| |
| 17:35 | <vsuojanen[m]> on semetary, i suggest 😀
| |
| 17:37 | <alkisg> From my personal experience, the really bottom score to be able to surf if you're using a single tab and you're willing to wait, is around 400 (yours have 187).
| |
| 17:37 | The "acceptable score for browsing if you don't have other programs open" is around 1000. And starting from 2000 score, you can have other programs open as well.
| |
| 17:37 | Recent CPUs have a score of 10000+
| |
| 17:40 | <Tomahock> yes, direct to /dev/null, eventually considering buying new thin clients, what model / brand could you suggest to use with LTSP ?
| |
| 17:40 | Sorry that this is not a group issue but on those same thinclients when we had the xendesktop 5 license we could make acceptable use of the Windows 7 virtual desktop and it loaded everything with an acceptable speed, that could be largely due to the ICA protocol from Citrix? Could it be understood that LTSP is another way of working, the whole
| |
| 17:40 | process goes on the client?
| |
| 17:41 | <alkisg> LTSP boots the clients. Then you can run programs locally, or use remote desktop tools. LTSP doesn't develop its own remote desktop tools, you use the existing ones
| |
| 17:41 | There's xrdp and x2go and a few others, there's even a citrix/ica client for linux if you wish
| |
| 17:42 | It's true that the proprietary remote desktop programs are more advanced than the open source remote desktop programs, e.g. they are able to forward an in-browser video to be decoded on the client, instead of decoding it on the server and sending huge amounts of data, like x2go would do
| |
| 17:44 | But in general, browsing, gaming etc have become so demanding that the thin client model gets less usage each year, in all OSes. Even when some big companies like google and nvidia tried remote gaming ,they mostly failed
| |
| 17:45 | So, you'd just buy normal clients, not "thin clients". And LTSP would save you the disks from the hardware side, and would make administration easier from the software side
| |
| 17:46 | So, for basic clients you'd go for 4 GB RAM and 4000+ cpubenchmark score, while if you wanted to keep them for some years more, you'd go for 8 GB RAM and 8000+ cpubenchmark score
