Performance rule of thumb: Network/disk io >> allocations >> function calls If your program is dominated by network or disk access, don’t bother optimising allocations. If your program is allocation bound, don’t bother optimising functions for inlining, loop unrolling, etc.
Replying to @davecheney
Or rather if your program is allocation-bound, throw out whatever awful abstraction layer is making it so. IO-bound is inherent. Allocation-bound is a design flaw.
