I have recently bought a Powerbook 1.67Ghz with 1 Gb ram and a 80 gig hd. I'm running a fully patched "erase and install" Tiger install. I have 0 page outs most of the time. The harddrive has plenty of space left. I love the screen, love the keyboard, and love the looks. However I'm quite dismayed at the performance. This laptop is roughly 3 years old and I don't think it should be this slow given the age but I would like to have some confirmation on it. Firstly, flash seems to bring this laptop to its knees. Watching a video on youtube and typing this message is causing me to use anywhere from 50-70% cpu usage(monitored using istat menu). 720p is unwatchable. Secondly, iWork '09 takes about 10 seconds to load. When I use it to open Word documents, including the conversion, it takes about 30 seconds before I am able to see anything. Lastly, my notebook runs very hot. After about 15 minutes of casual usage(firefox, itunes, iwork), the idle temp is ~52C. Is this normal? The reason I ask is that I realize that switching to Intel has done wonders to boost the performance of Macs, but is the G4 powerpc really this slow? It feels completely outdated and sluggish. Hell I can even type faster than words appear on the screen. Obviously I'm also a PC user but my 5 year old Dell laptop with a 1.2Ghz pentium M fares much better during multitasking. Under similar conditions when viewing youtube, my cpu usage would be ~20-30% and the processor peaks at ~50c. Is this because something is wrong with my Powerbook or are g4 processors just complete piles of dog manure?
