So the nodes that aren't on the wired network have unusually high loadavg/cpu usage. Checked the logs and it seems tunneldigger is doing lots of DNS lookups. (60/sec) I have changed beta (10.1.2.1) to use an IP address and the load average is low again (around 0.1). Since it is very convenient to use DNS for the exit node, we should hack the tunneldigger client to slow down. tunneldigger also seems to use more memory than it should (it uses 5MB). Alex
