Scenarios
Pages or jobs slow down at specific times. Flows, concurrency, data and performance objectives. The decision is documented with owners, boundaries and a concrete way to verify it.
Measure before changing
PHP performance optimization grounded in traces and real scenarios
We establish a baseline, locate where time and capacity are consumed, and verify every change against a scenario representing actual use.
BaselineLatency, errors, load and resources.
DiagnosisPHP, queries, cache, network and queues.
OutcomeRepeatable before-and-after comparison.
Visible slowness may have a different cause
More servers, caching or indexes can hide or move a problem. We first define the experience and load to protect.
- Pages or jobs slow down at specific times.
- The database shows high CPU, locks or long queries.
- Workers build a queue without known capacity.
- Caching improves some routes but creates inconsistency elsewhere.
- There is no repeatable scenario to validate changes.
From a symptom to a capability the team can operate
We do not treat each need as an isolated feature. We connect the problem to data, rules, dependencies, people and operations so the solution remains understandable after delivery.
Instrumentation
The database shows high CPU, locks or long queries. Layer timings, queries, resources, errors and queues. The decision is documented with owners, boundaries and a concrete way to verify it.
Bottleneck profile
Workers build a queue without known capacity. Evidence and contribution of each factor. The decision is documented with owners, boundaries and a concrete way to verify it.
Prioritized plan
Caching improves some routes but creates inconsistency elsewhere. Changes by impact, risk, cost and reversibility. The decision is documented with owners, boundaries and a concrete way to verify it.
Implementation
There is no repeatable scenario to validate changes. Code, queries, indexes, cache, workers or configuration. The decision is documented with owners, boundaries and a concrete way to verify it.
What the work leaves in place
Final scope is agreed against available evidence and the risk to reduce.
Flows, concurrency, data and performance objectives.
Layer timings, queries, resources, errors and queues.
Evidence and contribution of each factor.
Changes by impact, risk, cost and reversibility.
Code, queries, indexes, cache, workers or configuration.
Same load, known conditions and explained results.

How we know the work is creating value
For PHP performance we do not measure progress by code volume. We look for verifiable change in behaviour, risk, team autonomy and operating capability.
We first agree which situation must change and what evidence will demonstrate the outcome. It may be a flow no longer dependent on manual steps, a rehearsed recovery, a centralized rule or a signal enabling earlier diagnosis. Without that reference, a technically correct delivery may still miss the problem.
We then verify that the capability can be maintained: code is reviewable, data retains integrity, failures have a known response and important decisions do not depend on oral memory. Closure includes remaining boundaries and next priorities rather than a promise of perfection.
- Verified behaviour and acceptance criteria.
- Documented risks, assumptions and exclusions.
- Prepared release, observation and recovery.
- Accessible knowledge for continued evolution.
What must be decided with context
We make conditions and limits explicit to avoid universal recommendations.
Percentiles and capacity are more useful than an isolated average.
Only with ownership, invalidation and observation.
Remove unnecessary work before adding capacity.
Questions before starting
Answers about scope, evidence and ways of working.
Do you guarantee an improvement percentage?
Not before a baseline and scenario exist. We define measurable targets after diagnosis.
Is MySQL usually the problem?
It may be queries, PHP, network, services, data, cache or infrastructure; evidence decides.
Do you run load tests?
Yes, with safe data and traffic, agreed limits and an appropriate environment.
Will a CDN solve slowness?
Only the cacheable, distributable part; it does not replace backend diagnosis.
