Recently (last 3 months or so), Safari has developed a habit of bringing my entire computer to a screeching halt at regular intervals. Safari stops working for 30 seconds or more as the beach ball spins and, sometimes, the whole system fails to work during these slow downs. It's like temporary dementia.
I've look in the activity monitor and I notice that my CPU usage balloons during these mini collapses to more than 100% - sometimes as high as 160%. I switched to Firefox and it began to do the same thing. It doesn't seem to matter how many tabs I have open or what I'm actually doing at the time - I'm not streaming or receiving any data, just surfing.
I was initially concerned about a virus or trojan sucking out data at regular intervals. I wouldn't know how to track down nasties like this even if I did have one. I've run Onyx, repaired the disk, run software updates, restarts, etc. and the problem doesn't go away. Does anyone have any suggestions what might be causing this series of regular mini heart attacks for my computer? It's frustrating when every 20 seconds the beach ball freezes my iMac for 30-45 seconds at a time - and it seems to be because of a sudden and inexplicable surge in CPU use.
Thanks
