Page caching reuses responses; Redis may support object caching, sessions or queues according to the application. Add memory or CPU only when measurements show that resource is the relevant limit. When a page slows down, increasing the server is a hypothesis. Repeated queries, heavy images and external calls can also explain the delay. Separating these causes helps invest in the right resource and checking if the change improved the experience. Process overview - Measuring experience - Find the bottleneck - Fix or apply cache - Repeat measurement ## Observe the path of the request Measure the time in the browser and backend, identify time-consuming queries, and track CPU, memory, and disk in the same period. An external API wait can leave the page slow even with low CPU consumption. Compare a visitor access with an authenticated access. If only the logged area is slow, the diagnosis needs to include queries and customization rules. Avoid using a single average to describe all users. ## Each cache solves a part Page cache reuses an entire response when this is appropriate. Data cache can save an intermediate result to avoid repeated work. Redis is a component that can participate in this design, but the application needs to be integrated and have validity rules. WordPane stacks feature Redis among their support features. This does not guarantee that your plugin or application is already using the service. Confirm the configuration and test update, expiration and recovery when the cache is empty. ## Caution when reusing AI responses A public documentation question may have reusable content. A private data-based response should respect user, organization, and permissions. Do not use a generic cache key for different conversations. Also consider changes in the source of information: an old reply about price or availability may no longer be correct. Decide what can be stored, how long and how to invalidate the information when it changes. ## Measure different layers with different questions Server response time, visual loading and duration of a business operation are not the same. A page can respond quickly and display an image late; a checkout may seem light and wait many seconds for a shipping API. Identify which experience is bad before choosing the tool. Observe latency distribution and error rate beyond average. A small group of very slow requests can affect important customers while the average seems acceptable. Compare equivalent samples of content, cache, and load, and record what has changed between measurements. ## Redis needs a data policy and invalidation Define which data is cached, how keys are isolated by account and how long they remain valid. When data changes, determine whether the application invalidates the key or waits for expiration. A long TTL can reduce queries while extending how long stale responses remain visible. Available memory and eviction policy matter too. Cached data can be rebuilt; removing sessions or queue structures may have different consequences. Do not combine these uses without understanding each component’s durability, capacity and requirements. ## Example: catalogue with repeated query First identify the slow query and check whether it needs an index or a different access pattern. Then evaluate caching reusable results. If the catalog changes infrequently and receives many reads, caching can reduce repeated work. If every response is unique per user, reuse is more limited. Test a product update and measure how long it takes to appear. Then simulate cache unavailability: the application must remain correct, even if slower. If the cache becomes the only copy of important data, the persistence design needs to change. ## When increasing server capacity makes sense After reducing unnecessary work, observe CPU, memory, disk, connections and queues under the target load. Expand the resource limiting the working set and measure again. An application may need both query improvements and more peak capacity. In WordPane, take data from the longer-use period and describe the active processes. Redis available in the environment does not mean automatic integration with any application. Confirm the client, configuration, and recovery behavior used by your software. ## Validate improvement before zooming - Register an initial measure for important flows. - Make one change at a time and repeat the same load. - Check out errors and consistency of data beyond time. - Extend resources when measures indicate a lack of capacity. ## Choose the project environment Compare the plans or send the application requirements to the WordPane team.
