Alistair,

There are a lot of variables to consider when looking at speed of response to Fatbomb or any program:

- how many sources you're using for results
- overall server load
- the run priority of your programs
- network load within your ISP
- network path & traffic between your ISP & your sources

I'm using the newest Fatbomb engines, and I haven't noticed a slowdown.

You didn't say which sources you're using. You might want to remove all sources, except for one of the smaller ones like Wisenut, and see if that speeds things up. If it does, then you can add more sources one at a time until you see response slow down again.
