| ccz | hello | 21:45 |
| ccz | switching from ubuntu to xubuntu now | 21:45 |
| ccz | to fix some issues with the system | 21:45 |
| ccz | and... some persisted | 21:46 |
| gnrp | ccz: Like...? | 21:46 |
| ccz | all the system get stuck when i download something big (like a 20GB game) | 21:46 |
| ccz | i have a fast broadband and a ssd | 21:47 |
| gnrp | what does it mean that the system gets stuck? It is crashing, or getting very slow? | 21:47 |
| ccz | like almost all the operations freezes, if there is a video playing and a music running in spotify, both stop, the clock stops... | 21:48 |
| ccz | the only thing that works is the cursor | 21:48 |
| ccz | but the download keeps running in the background | 21:48 |
| gnrp | how do you know the download is running? | 21:49 |
| gnrp | what program do you use for downloading? | 21:49 |
| gnrp | how much free space do you have on your hdd? | 21:49 |
| ccz | it could be a download on firefox or a game on steam | 21:49 |
| gnrp | btw, this is not a xubuntu thing, you might get as well helped in any linux or ubuntu channel, I think^^ | 21:49 |
| gnrp | how do you know the download is still running? | 21:49 |
| ccz | yes, good idea, hehe | 21:49 |
| gnrp | do you see the hard drive working? | 21:49 |
| ccz | in 1 minute more or less, the system works again | 21:50 |
| ccz | and the download gets completed or sometimes corrupted | 21:50 |
| ccz | i don't know if its a bottleneck between the internet, ssd, memory and configurations in the system | 21:50 |
| gnrp | sounds to me as if your system is swapping and that freezes everything? | 21:50 |
| gnrp | how much free space do you have? | 21:50 |
| gnrp | and how is the usage of RAM? If you let a terminal with the program htop running inside, on the top you can see how much RAM is being used | 21:51 |
| ccz | lemme see... | 21:51 |
| ccz | 70GB | 21:51 |
| ccz | of free space in the ssd | 21:51 |
| ccz | this time when I downloaded CS: started downloading, the ssd was writing in 60MB/s and the internet following it. | 21:52 |
| ccz | after like 30s the pc stuck | 21:52 |
| ccz | the graph suddenly gets to 0MB/s | 21:53 |
| ccz | some seconds and it grows again, it's like a cycle | 21:53 |
| ccz | 70GB of 120GB on the SSD* | 21:53 |
| gnrp | where do you see the graph of the network usage? | 21:54 |
| ccz | in case of steam, in the downloads panel | 21:54 |
| gnrp | can you at the same point look at how much the hdd is writing? | 21:54 |
| ccz | yes | 21:54 |
| gnrp | that would be interesting | 21:55 |
| ccz | do you want a screenshot? | 21:55 |
| ccz | in imgur | 21:55 |
| gnrp | I mean, it is more interesting in terms of time | 21:55 |
| ccz | hmm | 21:55 |
| gnrp | my suspicion is that you download stuff which is not written to the HDD, and then at some point it is all flushed | 21:55 |
| gnrp | to confirm that, maybe try something like (entering into a terminal): while true; do echo "sync!"; sync; sleep 1; done | 21:56 |
| ccz | hmm | 21:56 |
| gnrp | this will perform a flushing of all pending filesystem operations every second | 21:56 |
| gnrp | well, until it is done | 21:56 |
| gnrp | so let that run in a terminal while the download is running and check what is happening. | 21:57 |
| ccz | i'll try... abou the CPU, I saw that it gets 100%, gets stuck, then drops to 60% and goes up gain | 21:57 |
| ccz | i'll try with other game here | 21:58 |
| ccz | thanks | 21:58 |
| ccz | ok I did it | 22:01 |
| ccz | I downloaded 700MB | 22:01 |
| ccz | with this sync! printing in the terminal... | 22:01 |
| ccz | in the middle of the download the "sync!" stop printing for a time | 22:02 |
| ccz | i thing 30s | 22:02 |
| ccz | think* | 22:02 |
| gnrp | yes, that is right | 22:02 |
| ccz | then the download finished | 22:02 |
| ccz | and the sync is still printing lmao | 22:02 |
| gnrp | it will perform that command until everything which was supposed o be written in that moment has been written | 22:02 |
| gnrp | press Ctrl+C in the terminal to close it | 22:02 |
| ccz | right | 22:02 |
| gnrp | so did your computer freeze now? | 22:03 |
| ccz | this time no... | 22:03 |
| ccz | nothing critical | 22:03 |
| gnrp | I got to go to bed now, but I guess with this you can go on searching for help. | 22:03 |
| ccz | (in the CS time, after I get back to the computer, "Ubuntu 20.4 ... is not responding" | 22:03 |
| gnrp | The issue is that for some reason your computer buffers all the downloaded data | 22:04 |
| ccz | very thank you | 22:04 |
| gnrp | and then your ram is full and only then it starts writing to the disk | 22:04 |
| ccz | it does make sense... | 22:04 |
| gnrp | I had this behavior with my systems as well with external drives, but never cared too much to actually fix it | 22:04 |
| gnrp | it does not really make sense, but that's how I suppose it is^^ | 22:04 |
| gnrp | the OS should start writing as soon as it can | 22:05 |
| gnrp | anyway, I gtg | 22:05 |
| gnrp | gn8 | 22:05 |
| ccz | thanks | 22:05 |
| gnrp | if you find a solution, I'd also be curious | 22:05 |
| ccz | really helped | 22:05 |
| gnrp | probably changing the scheduler might do the trick? | 22:05 |
| ccz | then i got back here | 22:05 |
| ccz | in #xubuntu | 22:05 |
| ccz | if i get the solution | 22:05 |
| gnrp | thanks! | 22:05 |
| gnrp | and gn8 | 22:05 |
| ccz | good night | 22:05 |
