</div>This proves anything... We used to have Ubuntu 6.06+LTSP4.2, now we have<br>
Ubuntu 8.04.1+LTSP5.<br>
<br>
2 servers, both have 2 x Dual Core Xeon and 6G memory. LAN is fast. We<br>
have 113 thin clients, HP t5125/5135.<br>
<br>
Here is video about one classroom (12 thin clients) on the other day.<br>
First some 2D games, then Gimp and then Flash games on the Internet.</blockquote><div><br>I am very pleased that you are satisfied because Ubuntu Hardy seems like at very god distro with all its eye-candy etc. I see that you are using true thin clients that works well. We have a lot of compaq-desktops that we use as thin-clients. They all have 128-512 MB ram. As i mentioned earlier it seems that there is a problem when the clients are "talking" to the fileserver when the pupils logs on that are generating a huge amount of stress on the fileserver that makes everybody and everything stall. 5-15 pupils are in a way acceptable. But when 20-30 pupils logs on, the fileserver is paralysed. (And again. Our fileserver is overkill). To me it seems like perhaps it is the clients that make some kind of wild NFS traffic towards the fileserver when they log on. And when none of these problems occured with K12LTSP with the same clients and servers I naturally believe that there is something strange in Hardy and LTSP5<br>
