pfSense UI freezes when a complex webpage loads

[lohphat]

In testing pfblockerNG and snort I was seeing a behavior when trying to load "pr0nhub.com" (URL obfuscated, you kids know the real one).

I assumed it was snort inspecting traffic so I stopped snort and pfblockerNG and the UI still froze for 30 seconds when I loaded the page.

Before I go down a rat hole, is this expected behavior?

The pr0nhub site is a massive page load with lots of small streaming video thumbnails, so it's pretty taxing but I'd hope the SG-3100 wouldn't break a sweat.

I'm running the release code at the moment.

I realize that comment is regarding the SG-1000 but the behavior is identical. I DO have the traffic graph widget on my top page, but I have seen the admin UI freeze on my SG-3100 on other pages when I'm testing the config by loading suspect pages on an internal host.
