Well in just the last few days while using my 17 in powerbook I have noticed it´s been slower than it used to be. So, I decided to run xbench and my results were about 5 points lower than about 2 weeks ago. Now, it's 87.15 and it used to be 92.7, I repaired disk permisions and erased some stupid stuff I downloaded, but my results were still the same. So, my question is...what are some things I can do to speed up my computer, besides buying memory? Does safari and internet explorer save internet files on the computer that slows it down, if so how do I erase these? Also, does the system log every action and save it somewhere which slows it down? Any help/advice is greatly appreciated!
