Re: [fw-core] Zend_cache_Backend_File too slow

I think if you are tagging a lot of cache entries it could be slow as
it needs to find the correct file to delete, this means (I assume) a
loop of the files in the directory.

Now maybe as filesystem operations are slow maybe you could use the
sqlite which I assume has faster lookup than PHP loop?

Also if you have one cache entry pre record, on update rather than
using a tag could you use the uniqueID instead?

$cache->remove('idToRemove');
