The standard solutions for controlling CPU isolation for low-latency applications under Linux are isolcpus and cgroups/csets. However, they each have their downsides and can be awkward to use.

Generate a highly efficient approach to generating an 8-byte lightweight identifier that is unique across many hosts, based on some predetermined partitioning by host identifier.

The cost of object creation can be far higher than the cost of cleaning them up if they are very short lived.

Techniques that help maximise hardware utilisation, while also reducing power consumption, helping reduce costs to your organisation.

Is replicating data to a secondary system faster than sync-ing to disk? My first time benchmarking with a realistic example.

Following the Hello World example, this article looks at an Order Processor with a New Order Single in and an Execution Report out.

Mapping large areas of memory avoids having to know in advance how much memory we need or having to resize the memory mappings while in use.

Let’s use an event-driven Hello World (a paradigm where the flow is determined by events) to step through behaviour-driven development,

How to use Behaviour Driven Development to establish the requirements from users, and Event Driven Architecture to automate testing!

…The Fewer the Words, the Greater the Profit.” And more wisdom and insight from Peter Lawrey, covering a range of development approaches.
