latest tuxpaint and tux suite apps... but it happens on all of them
since at least a year...
gigabit network... its definitely not the network... as even google
earth and video streaming work fine without bringing as many computers
We see the slow down on our dual xeon processor server with 16 gigs of
ram with only 10-15 users starting up the tux suite. Its the most
dramatic slow down and freeze of any software on the thin client
systems, and we're trying to figure out why.
here is a related bug post:
I can test some other non tux4kids SDL stuff if you like, but I know
gcompris and childsplay work much better... Over the next couple days
I'll try running a bunch of other SDL stuff and see how it fares
compared to tux4kids stuff...
anyway here are the version numbers:
If you need anything else, let me know
David Van Assche
Ubuntu 8.04.1 Desktop (i386)
100MBit network/Thin-clients, 1GB link to LTSP server
All thin-clients were at least PII 500MHz w/256MB RAM (older Compaq iPaqs)
Latest version of Tuxpaint:
jerickson@Fibonacci:~$ apt-cache show tuxpaint

This has been an issue since Gutsy (7.10). I recall talking with one of
the developers a long time ago, he seemed to see something pretty basic
as to at least speed things up a bit that had to do with SDL
refreshing or something (it's been a LONG time so forgive me if I'm wrong).
Has there been any progress on this.
I have the same problem.
Set up a ltps server running Ubunti 8.04.1 (With the Edubuntu add-ons) on a dual xeon 2.5GHz server.
When I boot up just 1 thin client (IBM Netvista 300MHz w/128MB RAM) I can run everything else acceptable Firefox / open office / etc.. but when I launch TuxMath it grinds to a halt and uses 100% of one processor on the server. We have a dedicated 100Mb network.
