The Asimo robot from Honda has been around for over a decade, so at first the humanoid robot from Toyota might not seem like much of an achievement. Perhaps this is true…but after watching the video you will have to agree its still pretty darn cool. Apparently the Toyota robot can only operate on conventional flat surfaces, whereas the Asimo robot is capable of walking up stairs and handling more diverse situations (except when it falls).
Under perfect circumstances a totally untweaked EBS drive running an ext3 filesystem will get you about 80kb read or write throughput and 7000 seeks per second. Two disks in a RAID 0 cofiguration will get you about 140kb read or write and about 10,000 seeks per second, this represents the best numbers I’ve been able to get out of an EBS disk setup as it seems to be saturating the IO channel on the EC2 instance. (This makes sense as it would be about what you’d expect from gigabit ethernet). However, when the EBS drives are NOT running their best, which is often, you need a lot more tweaking to get good performance out of them.
