Hi, I have installed onto my trusty Power Mac G5 Spec: Processor Speed: 2.3 GHz Processor Type: PowerPC 970fx (G5) x2

However it seems very slow this evening - seems to use up to 90% of CPU just to run basic web pages? I checked using istat and Activity monitor.

Another odd thing, on system profile it has processor down as single G5? Is that correct? Thought there were two?

    Your system should indeed be a dual CPU. TenFourFox has no control over that, and it is entirely possible the performance problems you're experiencing may actually be impending hardware failure. On my quad G5, System Profiler reports four CPUs (two cores each on two physical processors).

    For the record, I routinely use a 1GHz iMac G4 with TenFourFox. It's not super speedy, but it's certainly functional.
