----------------------------------------------------------------------------------------------

                 Key: ISPN-1291
                 URL: https://issues.jboss.org/browse/ISPN-1291
             Project: Infinispan
          Issue Type: Quality Risk
          Components: Loaders and Stores
    Affects Versions: 5.0.0.CR8, 4.2.1.FINAL
            Reporter: Robert Stupp

Purging in FileCacheStore takes too long.

I have implemented a copy of FileCacheStore with the issues of ISPN-1286 resolved.
So the purgeInternal will both not block the whole application (uses cache key locks instead of a global lock and a large purge interval).

When adding a huge amount of data, the FileCacheStore writes many many thousands of files.
During each purge, all files will be touched - so the time to purge increases until it is no longer acceptable (several minutes to several hours).
