One thing you need to be careful with on these benchmarks is memory usage. Especially targeting the ps3, memory is not exactly free. Same for throughput of data if you require anything off of the disc. So, how long does it take to read a meg off the disk and process it as program data? In other words, these benchmarks are likely completely irrelevant. Also, you keep looking at stack allocation and unsigned types. I think the more important "unsafe" trick is the ability to memcpy into a struct. The unsigned part is one thing, but actually being able to say the next "5k bytes from the disc is an array of this struct" is huge. Well.... I say that. It sounds huge. I could definitely be wrong. :) -- You received this message because you are subscribed to the Google Groups "The Java Posse" group. To post to this group, send email to [email protected].
