Description

Having the traffic graphs open will slow networking down by a given percentage for each instance of the graphs open. Running pfSense 2.0.1 on a Soekris net6501-70. With a 100Mbps internet pipe, we were running speed tests. We are able to get over 90Mbps. Roughly 30% of network bandwidth is lost for every instance of the traffic graphs open. The CPU bar indicates usage is not excessive. With enough instances open, we were able to get speeds as low as 40Mbps.

These boxes are running Intel Atom Processors at 1.6GHZ, with 2GB of RAM, doing basing routing/NAT.

That's just a side effect of using the GUI. The more things that are open and checking in the GUI, the more resources get used by PHP and lighty, and the less resources that are available to the system for things like network processing.

Worth trying on a recent 2.1 after the latest php+lighty changes, it may not be as intensive now.
