In this paper, we describe various data caching scenarios test implementation and lessons learned. In particular, we show how local data caches may be configured, deployed, and tested. In our studies, we are using xCache, which is a special type of Xrootd server setup to cache input data for a physics analysis. A relatively large Tier2 storage is used as a primary data source and several geographically distributed smaller WLCG sites configured specifically for this test. All sites are connected to the LHCONE network. The testbed configuration is evaluated using both synthetic tests and real ATLAS computational jobs submitted via the HammerCloud toolkit. The impact and realistic applicability of different local cache configurations is explained, including both the network infrastructure and the configuration of computing nodes.
