Not all reports are required to be shown with real-time data, hence if the report can be internally saved with initial execution and can be used as a pre-loaded report for next request, it will surely shorten the time for satisfying user's request as it does not need to spend time on processing the report along with data extraction. This can be achieved by caching the report.
For improving the overall performance there are some important settings that you need to understand if you want to cache the report. Remember, if you enable caching, you need to make sure either it get's expired based on a pre-defined time-frame or it is linked with a Cache Refresh Plan. Otherwise, the report will deliver with the cached copy even though new data is available at the source.
Most common technique used for caching the report is, generate the cache with the initial request and set a time-frame for removing the cache. Once the cache is removed, the next execution processes the...
