Objective-C implicit conversion loses integer precision 'NSUInteger' (aka 'unsigned long') to 'int'
...t seen any difference. It will only make a difference in apps that use the CPU heavily - games for example would see a benefit compiling for 64 bit.

Why can't enum's constructor access static fields?

When should I use Lazy?
... I believe the main trade-off is between memory usage (lazy) and cpu usage (not-lazy). Because lazy has to do some extra book-keeping, InitLazy would use more memory than the other solutions. It also might have a minor performance hit on each access, while it checks whether it already has ...

When to use reinterpret_cast?
...ic_cast stands for.
On the other hand, when you call reinterpret_cast the CPU does not invoke any calculations. It just treats a set of bits in the memory like if it had another type. So when you convert int* to float* with this keyword, the new value (after pointer dereferecing) has nothing to do ...

I'll proceed with the assumption that your "service" is a CPU-bound operation that must execute on the same machine as the web server.
If that's the case, then the next thing to evaluate is another assumption:
I need the request to execute faster.
Are you absolutely sure that...
