I think you really ought to put more RAM at the top of the priority
list!!!!  I have a mini-lab with only 10 clients and it has 1 Gb RAM.

I think that you may be running too many terminals with too little RAM
and probably the 10mbps is also another potential problem when all 25
clients are logged on.

Did you find that the server "swapped" off the hard drive very much?  I
would think that you're hard drive would be going crazy trying to keep
up with the demands (because the RAM couldn't keep up).

The problem may have nothing to do with it being K6-2.  I'm using a few
K6-2 @ 150 Mhz with 32 Mb RAM and they're fine (though not nearly as
fast as my P-II 450 Mhz w/ 64 Mb RAM clients).  I think the trouble is
in the video driver...  Can you find the old video driver that WAS
working before (or did your server autodetect it?)? If you can find it
then, you could specify that workstation to load that video driver in
your lts.conf.

Your english is fine!  I respect that you are multi-lingual: Brazilian
(Spanish, right?), English and Linux-ese.  ;-)
