Slow WebGUI
-
I've been using pfSense for several months now and am quite happy. However, for the past few days the WebGUI has been extremely slow in responding. CPU usage hovers at around 1%. Load averages are 0.06, 0.09, 0.06, RAM is 39% of 2G, MBUF is 6%, State table is <1%. When I do anything in the GUI, it can take as long as 10-20 seconds to respond, whiich makes using pF very painful.
Any ideas?

Does your configured DNS work?

As far as I know. I've got 4 DNS configured; two internal, two external. The servers serve everyone else on the LAN, so I'd know pretty fast if there were problems. Manual resolves work on all 4 servers. However, I think I might have it figured out. I'm running pfSense in a virtual machine that lives on an HP LeftHand dual-node RAID5 (don't ask) SAN cluster. A week ago, one of the drives failed and I am still waiting for a replacement from HP. In the meantime, I'm thinking that the write overhead increase due to the missing drive may be adversely affecting performance. I notice that the GUI is slow in most things, but other functions fly. The slow functions seem to be write-related, which led me to the suspicion about the missing drive. If the nodes are set to write back when OK, but write-through if degraded, then that would explain it.

Sorry, I forgot to update this.
It turns out the problem was the interface that the DNS Forwarder was set to. I stupidly changed it from Localhost to LAN, and never noticed how that borked DNS lookups and caused the GUI slowdown. Once I put it back to Localhost from LAN, everything was fine. Thanks to JimP for that one.

you mean follwoing setting:

–DNS Forwarder
--- Under Interfaces Localhost?

Under Interfaces Localhost?
Quite the old thread you have unearthed, but the answer is yes.
