Andrew Hunter makes code really, really fast. Before joining Jane
Street, he worked for seven years at Google on multithreaded
architecture, and was a tech lead for tcmalloc, Google’s
world-class scalable malloc implementation. In this episode,
Andrew and Ron discuss how, paradoxically, it can be easier to
optimize systems at hyperscale because of the impact that even
miniscule changes can have. Finding performance wins in trading
systems—which operate at a smaller scale, but which have bursty,
low-latency workloads—is often trickier. Andrew explains how he
approaches the problem, including his favorite profiling
techniques and tools for visualizing traces; the unique
challenges of optimizing OCaml versus C++; and when you should
and shouldn’t care about nanoseconds. They also touch on the joys
of musical theater, and how to pass an interview when you’re
sleep-deprived.
