Where aws ends and the internet begins is an exercise left to the reader. Dynomite is a Netflix open source wrapper around Redis that provides a few additional features like auto-sharding and cross-region replication, and it provided Pushy with low latency and easy record expiry, both of which are critical for Pushy’s workload.

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. sounds like a homework exercise of purely academic value. A firewall was blocking everything – the reported latency was the time it took the client to time out! Do it less.

The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. Each of the two vector units can issue one FMA instruction per cycle, assuming that there are enough independent accumulators to tolerate the 6-cycle dependent-operation latency. Instead, we found puzzle after puzzle.
