Ehcache uses a tiering system. Yes, an entry that was just read from the cache is likely to be promoted in to an in-memory tier (offheap and/or heap).
Additionally, your OS is likely caching your file system, so a second lookup is likely to be faster even if from disk.
Lastly, 2 seconds is an eternity. Guessing that the disk is maybe virtual/network based? Are you also measuring JVM warm-up (JIT) time?
