Description

In network-mounted drives, a user can experience long processing time due to File#length and File#lastModified large invocation time.

 

Use case: 

There is a network-mounted drive. A user is polling a directory with thousands of files inside, but only needs to process few of them. 

 

Current behaviour:

File length and last modified attributes are read for each such file, seriously slowing the processing time.

 

Expected behaviour:

File length and last modified attributes are read only when needed.

 

Affected method is FileConsumer#asGenericFile. A solution for this can be to load these two attributes lazily.
