Haven't timed mine but I thought it was slow too at around 30seconds on an SP13000 with 512Mb Ram.
Sounds like something wrong on yours.
I also notice that when the outside temp is above 26 degrees C that my PC's CPU runs at between 55 & 80 degrees C, and once it passes 75 is pretty useless and unresoponsive - I wonder why Impending melt down maybe!!!
Just keep an eye on the temps if its behaving erratically
