Description
currently the "flush by tag" command is painfully slow when using file cache backend.
This can be improved e.g. by using tag index (one file for each tag, containing id's of the cache entries)

you can test the performance of this file cache backend by using my tool

For Patchset 2¶
Flushing is over 100times faster, but unfortunatelly write is 2x slower.

Is this issue still relevant despite the performance issues?
