So, could it be that the ltspbr0 bridge is a source of the issue?

I don't think that should impact performance much at all. IIRC the chroot memory footprint in K12Linux is still higher than K12LTSP. That might be part of it, if your clients have less that 128MB of memory.

Or
using nbdswap for the clients?
Actually, NBD swap is supposed to be faster than NFS swap, that's why the developers implemented it.


Any ideas on how to tell?


I thought it might be the LDM_DIRECTX setting, but that is set to TRUE by default on Fedora, which means that X traffic isn't encrypted on K12LTSP by default. So it must be something else. Higher network traffic for some reason, like increased screen resolution or color depth? You said the server has plenty of memory and CPU, and I don't think the disk IO should change that much.

Sincerely,
Dave Hopkins
