8.04 ltsp +slow

[Uwe Geercken]

hello friends,

I have a similar problem. I have re-installed the server. I went to  
8.04 and at the same time implemented software raid to our server  
which had been running several month in our local school.

now when the server starts the following happens: the first client  
that boots is really fast. the second one is visibly slower. all other  
clients (all the same) don't boot anymore after that. we are alone on  
the network: just the edubuntu server and 15 clients.

when I shutdown the clients and reboot the server and then start  
different clients, I experience the same problem. also maybe I should  
add, that with the previous version we did not experience these  
problems.

when I try to boot several clients as described above and then go to  
the server, I noticed that the server is really slow: even entering  
the root password on the console takes forever.

hope somebody can help me. it is rather urgent, as I have to start  
classes 6 days from today and the kids (11 years old) want to fell and  
see some linux and I really don't want to disappoint them.

tks.

uwe
