Why might report generation be slow when running a report for the first time?

When running a report for the first time, the system may need to create hcache, which stands for "hash cache." This cache is utilized to store the results of the generated report in a manner that allows for faster access in future requests. During the initial generation of the report, the system must compile all required data and organize it effectively, which can take significant processing time. Once the hcache is created, subsequent requests for the same report can be significantly faster since the system can draw upon the preprocessed data instead of recalculating everything from scratch.

While other factors such as network quality, server load, or report complexity can affect performance, the creation of hcache is specifically pertinent to the delay experienced during the initial report generation process. Subsequent runs of the same report will benefit from the cached data, resulting in a faster response time.
