Assorted links for Monday, April 7:
- The Lost Xperf Documentation–Disk Usage
As I’ve lamented previously, the documentation for xperf (Windows Performance Toolkit) is a bit light. The names of the columns in the summary tables can be exquisitely subtle, and I have never found any documentation for them. But, I’ve talked to the xperf authors, and I’ve used xperf a lot, and I’ve done some experiments, and here I share some more results, this time for the Disk Usage summary table.
- The macro problem with microservices
In just 20 years, software engineering has shifted from architecting monoliths with a single database and centralized state to microservices where everything is distributed across multiple containers, servers, data centers, and even continents. Distributing things solves scaling concerns, but introduces a whole new world of problems, many of which were previously solved by monoliths.

- FioSynth: A representative I/O benchmark and data visualizer for data center workloads
FioSynth is a benchmark tool used to automate the execution of storage workload suites and to parse results. It contains a base set of block level storage workloads, synthesized from production I/O traces, that simulate a diverse range of Facebook production services. It is useful for predicting how a storage device will perform in realistic production environments and for assisting with performance tuning.
- Azure Container Registry Adds Teleportation
Project Teleport removes the cost of download and decompression by SMB mounting pre-expanded layers from the Azure Container Registry to Teleport enabled Azure container hosts.
