The speed of an application is one of its most important features — and the WP Software License plugin is engineered with that in mind. Its core code is highly optimized: enabling the plugin adds only about 0.07 seconds to a typical page request when inactive code paths are avoided, so the plugin itself does not become a bottleneck. Fast execution improves user experience, reduces bounce rates, and — importantly — helps with search visibility since Google favors quicker-loading pages.
On WordPress sites many components run on every request: theme code, other plugins, and the WordPress core. As a shop grows, API interactions (license checks, product updates, activation checks, domain protection) rise too, consuming CPU, database I/O and memory. On modest hosting plans this growth can push response times up and sometimes force site owners to pay for costly hosting upgrades or risk resource throttling by the provider.
That’s why we built the proprietary Cache Module — a lightweight, purpose-built caching layer for API interactions. Instead of executing a full WordPress call for each client request, the Cache Module stores recent API responses and serves them in microseconds. On cache misses it falls back to the normal process, then stores the result for subsequent requests. The cache supports configurable TTL (time-to-live) and automatic invalidation when a license or product is updated, so data remains fresh without constant recomputation.
Performance tests clearly show the benefit: the Cache Module is roughly 35–37× faster than a standard WordPress API call. In one benchmark of 1,000 API interactions, a server using the Cache Module completed processing in about 114 seconds, whereas the same workload without caching required more than 4,200 seconds. Practically, this means one regular $14/month server can safely handle many more clients and frequent automated product updates without immediate migration to higher-cost hosting.
The overall speed on a large number of interactions (1000 calls), a regular server will require 92 seconds to process the data requests, while on other plugin 4259 seconds (near 71 minutes), away much longer.
Benefits at a glance
- Massive reduction in API processing time — supports thousands of interactions per day with low resource usage.
- Lower hosting costs — scale further on the same infrastructure.
- Better reliability — lower risk of account throttling or suspension due to resource spikes.
- Simple deployment — enable it from the WordPress admin: WooCommerce > Settings > Products > License Products → check “Use Cache Module for API interactions.”
- Safe defaults — cache falls back to live checks for misses and invalidates on updates to keep data accurate.
In short, the WP Software License plugin plus its Cache Module delivers faster API performance, reduced server load, and smoother scaling — giving shop owners a cost-effective way to keep license checks and product updates fast and reliable as their customer base grows.
The Cache Module can be enabled through WordPress Dashboard at WooCommerce > Settings > Products > License Products, the Use Cache Module for API interactions checkbox need to be checked.
