<eu^31134183200>
hello! how could create i386 image?
16:26
<alkisg>
eu^31134183200: new or old ltsp?
16:26
<eu^31134183200>
new
16:26
<alkisg>
Create a VM
16:26
Use virtualbox
16:26
vmdk format, static size
16:30
<eu^31134183200>
and then? :)
16:31
<alkisg>
You symlink the vm to /srv/ltsp/x86_32.img
16:31
and you run ltsp image x86_32
16:31
See the ltsp image man page
16:31

<alkisg>
Sure

hi alkisg :) No problems right now, just I'm a bit scared about boot/load time with new distro (20.04) + new ltsp, I've tried the old 14.04 and was much faster (2x?). Is there any "profiling" tool that helps find if there is something obviously wrong? Something that stalls, dns problems, don'tknowwhatelse?
16:52
<alkisg>
markit: try normal ubuntu, isn't it a lot slower than 14.04?
16:52
<markit>
and also, could it be a KDE problem or you noticed the same with Mate?
16:53
<alkisg>
I don't think it's relatedto ltsp
16:53
<markit>
i.e. 14.04 kde was 2x slower than Gnome/whaterver you used, because of stupid I/O for building a "icon cache"
16:54
I was able to figure out and try to mitigate, but was a nightmare because I've no the skill to be able to log "what is doing I/O, disk and lan"
16:55
any suggestion? I can use iotop -o and iftop but is just coreography since does not store data that you can check later
16:56
<alkisg>
Test with normal installations without ltsp
16:56
That's my suggestion
17:03
Ubuntu had optimized boot time for 10.04; I had booted ltsp clients in 10 secs then
17:03
After that, they didn't care much and things got slower again
17:03
As long as it boots in under a minute, it's ok for me though

<alkisg>
markit: if you're suspecting that kde writes a lot of temporary data, you can check in /run/initramfs/ltsp/up
18:27
That directory contains the changes after boot
