How we measured
We measured the same homepage, server and guest context in alternating cache-off and cache-on blocks. No global server performance settings were changed.
These are server response timings, not full page load times. Results depend on the store, hosting, theme and traffic.

Request an optional personalized audit for 100 €. Work starts after payment and SSH verification. The audit provides findings and a prioritized action plan; implementation is quoted separately.
SSH access is required before you order.
Confirm with your hosting provider that SSH access and sufficient permissions are available. FTP or SFTP alone may not provide a command shell.
Hosting restrictions may prevent some changes, even when SSH is available. An audit does not guarantee that every recommended improvement can be applied.

Questions before you start
How does the 7-day free trial work?
Start your subscription in Stripe with a payment method. Your first charge of 3 € per month plus applicable taxes is due after the 7-day free trial. Cancel before the trial ends from your Devman account to avoid any subscription charge. No commitment.
Does it need LiteSpeed?
Performance Pro uses a local file cache after OpenCart starts. It does not require LiteSpeed. Host-level cache, Redis, CDN purge and prewarming are not included.
Will it work with my theme?
Tested cores: OpenCart 1.5.6.4, 2.0.3.1, 2.1.0.2, 2.2.0.0, 2.3.0.2, 3.0.3.8 and 4.1.0.4. Custom themes, pricing rules, imports and other extensions still need a staging compatibility check.
Will my score reach 100?
Results depend on hosting, theme, traffic and external scripts. Measurements show observed changes; they do not prove that a single change caused the result. No score or speed increase is guaranteed.
What happens if I stop paying?
If Devman is temporarily unavailable, local acceleration continues until the signed trial or paid-access deadline. A confirmed revocation disables it; your store keeps working.
Where are measurements stored?
Visit samples stay in your OpenCart storage. Only aggregate statistics are sent to Devman when you open the dashboard. The beacon does not collect full URLs or customer identifiers.
The interface follows the active OpenCart administrator language. English is the default for unsupported languages. English, Spanish, German, Russian, Ukrainian, Portuguese (Portugal), French and Italian are included.
