Subject DO NOT REPLY [Bug 46088] Performance (speed) of large path(s) must be improved.

Some of the resource collections do have a 'cache' attribute.  Further, most
places that accept paths should accept other resource collections, so a simple
workaround for you would be to wrap your path in a union resource collection
(cache defaults to true).  Contrary to your assertion that paths, filesets,
etc. are considered to be immutable, pre-Resource Collection versions of Ant
worked by re-scanning for files (e.g. when getting the members of a fileset, of
which it was and is possible to compose paths).  When path was retrofitted as a
resource collection it actually did originally cache results, leading to bug
41151 (a regression).  As an additional measure we could propagate the 'cache'
attribute directly to path to be passed to its underlying union (the original
cut of path as a resource collection extended union and thus did support this
attribute, but this was never released).
