| 19:59 | <nikoh77> hi, now my server work without problems, i can tweek it
| |
| 19:59 | spaced0ut has joined IRC (spaced0ut!~spaced0ut@unaffiliated/spaced0ut) | |
| 20:00 | <nikoh77> can i start server without start de? would it usefull?
| |
| 20:02 | <alkisg> It would save some MB RAM
| |
| 20:02 | How many thin clients do you have, how many fat, and how much RAM on the server?
| |
| 20:10 | E.g. if you just remove snapd, you save 10 times more RAM...
| |
| 20:15 | <nikoh77> 4/5 thin
| |
| 20:17 | the server is virtualized by proxmox
| |
| 20:19 | the real problem is latency to redraw windows eg when i move a window
| |
| 20:28 | <||cw> on the clients?
| |
| 20:28 | on the server via the web gui?
| |
| 20:28 | try vnc direct
| |
| 20:28 | <nikoh77> web gui? no no on thin clients
| |
| 20:29 | <||cw> are they 100Mbit or 1Gbe?
| |
| 20:32 | <alkisg> Saving RAM on the server doesn't help with latency
| |
| 20:32 | LDM_DIRECTX=False and more network cards can help
| |
| 20:32 | Are you sure you can't use them as fat clients?
| |
| 20:32 | Also, virtualization makes things a bit worse
| |
| 20:38 | adrianor1 is now known as adrianorg | |
| 20:40 | <nikoh77> the problem of fat client configuration is limit one session that dont disconnect first client.... in my experience
| |
| 20:52 | <alkisg> nikoh77: I don't know what you mean with that
| |
| 20:52 | lts.conf does have directives to limit one session, if you want that
| |
| 20:52 | And fat clients don't have display lags like thin clients
| |
| 20:58 | <||cw> if you're running thin on a vm server make sure you're using virtio for nic and storage. my KVM guest nics match host performance with virtio, but not with rtl or e1000
| |
| 21:07 | adrianor1 has joined IRC (adrianor1!~adrianorg@177.18.98.103) | |
| 21:09 | <nikoh77> i use intel e1000
| |
| 21:09 | adrianorg has left IRC (adrianorg!~adrianorg@177.18.180.168, Ping timeout: 246 seconds) | |
| 21:09 | <nikoh77> virtio is better?
| |
| 21:10 | <||cw> loads better.
| |
| 21:12 | try "iperf -c <server> -w 65536 -p 12345 -t 60 -P 4 " sometime
| |
| 21:12 | "perf -s -w 65536 -p 12345 -I 5" on the server
| |
| 21:13 | <nikoh77> ?
| |
| 21:13 | <||cw> benchmarking...
| |
| 21:13 | <nikoh77> ok ;-)
