Java Consulting in Swansea

Java advice for Swansea organisations, where a large share of performance complaints are configuration rather than code. The runtime has substantial tuning surface — heap sizing, garbage collector choice, how it perceives the resources available to it — and an application running badly in a container is frequently one that was never told what it had.

Why this comes up

The problem

The service is restarted regularly for memory reasons, and nobody has looked at how the runtime is configured.

What you get

What we deliver

  • Runtime configuration reviewed against the resources actually allocated
  • Garbage collector chosen for the workload rather than left at whatever defaults
  • Heap and memory limits set so the runtime and the container agree
  • Actual behaviour profiled before any code is optimised
  • Version position established, since long-term releases have defined support
  • Build and dependency management rationalised where it has accumulated

Java Consulting in Swansea — common questions

Why does container configuration cause problems?
Because the runtime sizes itself from what it believes is available. Where its view and the container's limit disagree, it plans for more memory than it can have — and the result is a process terminated by the platform rather than an error you can read.
Does the garbage collector choice matter?
For latency-sensitive services, considerably. Collectors trade throughput against pause time differently, and a service where occasional pauses are unacceptable benefits from a deliberate choice — while for batch work the default is usually fine.
Should we profile before optimising?
Always. Java performance intuition is unreliable because the runtime optimises aggressively at execution time, so code that looks expensive may cost nothing and the actual hot path is frequently somewhere nobody suspected.
How should we handle versions?
Target long-term support releases and move between them deliberately. The cadence is published with defined support windows, and staying on a supported release is considerably cheaper than recovering from several versions behind. It also matters commercially, since some distributions charge for extended support on versions that have passed their free maintenance window.
