Backend performance optimization for PHP applications
Slow pages, overloaded servers and jobs that run for days — diagnosed with measurements and fixed where it matters most.
When to call us
Typical symptoms
- Pages get slow under load, or are slow all the time.
- PHP-FPM workers are saturated and the server is at its limit.
- Database queries get slower as data grows.
- Imports, synchronization or calculations take hours or days.
- Hosting costs grow faster than traffic.
Results

- Batching, queues and background processing
Process
How it works
Measure
Establish a baseline: what is slow, how slow, and under what conditions.
Find
Profile and locate the bottlenecks that actually matter.
Fix
Highest-impact changes first, without breaking business logic.
Verify
Measure again and document the before-and-after.
Deliverables
What you get
- A diagnosis report with measured bottlenecks
- Implemented optimizations
- Before-and-after measurements
- Recommendations for keeping performance under control
FAQ
Frequently asked questions
Can you guarantee a specific speed-up?
No — and be careful with anyone who does before looking at your system. We measure first and give realistic estimates after diagnosis.
What access do you need?
Ideally access to the code, a copy or replica of the database and production metrics or logs. We agree the details before starting.
Do you only tune servers?
No. The biggest gains usually come from queries, data access patterns and business logic, not only from configuration.
How is pricing determined?
Pricing is on request and depends on scope. Project-based work, consulting and contract engagements are all possible — describe the task and we will propose a format.
Is your application too slow?
Describe the situation in a few sentences. We reply by email, usually within two business days. Pricing on request.
