One major complaint about One Laptop Per Child's XO laptop, is the speed of its Geode LX 700 CPU that runs at 433mhz. Most experienced computer users find it a little slow, and often compare it to computing in the late 90's.
On the other hand, OLPC's target market, children in the developing world who don't have a Dell or Xbox for comparison, don't seem to mind.
Still, for the serious geek, there is an easy fix for a slow processor: overclocking. Our field tester results:
For the record. 566mhz is a 30% improvement in processor speed over the stock 433mhz, and 233mhz is a 40% improvement in memory speed over 166mhz.
On average, I saw a 21.8% improvement in usable system speed at these overclocked ratings.
