If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Using simple lookup indices in Cassandra gives us the ability to maintain acceptable read latencies while doing heavy writes.

In one request hitting just ten services, there might be ten different analytics dashboards and ten different log stores. Telltale provides Edgar with latency benchmarks that indicate if the individual trace’s latency is abnormal for this given service. The downside is that we have so many dashboards.

Doing a good job in an uneven network environment requires thinking about availability and engineering for resilience and a lightweight footprint — always better to avoid testing the radio gods than it is spending weeks or months appeasing them after the damage is done.

The HammerDB TPROC-C workload by design intended as CPU and memory intensive workload derived from TPC-C – so that we get to benchmark at maximum CPU performance at a much smaller database footprint. For TPC-C this meant enough available spindles to reduce I/O latency and for TPC-H enough bandwidth for data throughput.

But hold your horses—before switching them to "block" mode, it's crucial to test them extensively. After you've researched, closed breaches, and tested, you start all over again. It's an ongoing, iterative process.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

Using a global ASP as a benchmark can further mislead thanks to the distorting effect of ultra-high-end prices rising while shipment volumes stagnate. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. Today, either method returns a similar answer.
