I have a new install of FreeNAS 9.10 running on bare metal. The web gui performance was working fine until I enabled NIS and then some pages like System --> General or Advanced get stuck at Loading.... and then eventually error out. The rest of the web gui pages work fine as expected. If I disable NIS then the problem goes away. Enable NIS and the problem comes back. I have another FreeNAS server the same version and also using NIS that works fine all the time so I don't think it is my connection to the NIS server. I am able to setup datasets and configure almost anything that does not rely on those web gui pages. Thanks for any input.
