I'm getting the figures by running 'top'. e.g. 18 clients produce a constant load of 16%. I can see where you're coming from. If I log to the file rather than tail -f in real time it's a bit better, but you need a lot of clients to be able to notice it. I've started replacing LXDE with KDE. It's slower, but we'll be able to have all the clients connected at once. I've also tried asking on my distro list. Nada. Hi The problem is that each Linux client adds 0.7% to smbd.
