Is it just me, or is LTSP a mess?

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
