Yes. When our application has 100,000+ objects, the increase in memory
also raises the working set significantly. That is, cache and paging
activity increases, so the application performance decreases.
I realize that some (all?) alpha processors do not handle 1-byte data
efficiently. I hope that the situation will change with future
versions. But it's hard to believe that alphas don't have an efficient
instruction set for (4-byte) int data. What about short data? Are they
handled as badly as 1-byte data?
I would prefer that bool be implemented with the best performance in
mind, including the effects of using memory efficiently, too.
