Slow USM with particular settings

Hi,

I am adapting a workflow from a Photoshop action and there is one step that does haze removal with USM using radius 60, amount 0.30 and threshold 1, that is extremely slow. I just timed it on a 94.4MB 4048x3040 photograph and it took 3 minutes, 50 seconds. I have a tile cache of 256MB and all other operations that I do are pretty fast. Is it expected that USM will be slow with such large radius settings or is this a problem? I'm using version 2.0.0 on Linux. I need to get round to compiling the latest version but don't know if that would affect this particular issue.

Cheers.
