If the stronger machines have more RAM, you could use FAT_RAM_THRESHOLD
to specify which clients should run as fat and which thin. So in your
lts.conf you could have something like:
In the above example, machiens above 512MB or RAM will start a fat
client session. A machine with more than 512MB of RAM can be set to use
a thin client session by using the LTSP_FATCLIENT directive.
