HFT needn’t mean low latency is required but of course the two tend to be related. If trivial allocations might cost you a microsecond then you can’t allocate at all on a latency-sensitive critical path and should probably get a better allocator. Also, be wary of power-of-two sized things because if they are aligned they are likely to have poor cache performance (too many things compete for the same set of cache lines). |
