Key Points
Literal arguments and inlining, when combined, provide significant opportunities for a compiler to provide significant performance improvements.
Inlining may backfire, and overly aggressive inlining will almost certainly do so. Inlining can increase code size. Large code size suffers a higher rate of cache misses and page faults than smaller code.
Nontrivial inlining decisions should be based on sample execution profiles, not gut feelings.
Consider rewriting high frequency methods with large static size and small dynamic size to extract their significant dynamic characteristic, and then inline the dynamic component.
Trivial and singleton methods can always be inlined.
