[TYPO3-core] RFC: No-brainer #15196: Speedup t3lib_cache_backend_DbBackend::has($entryIdentifier)

[Michael Knabe]

Hi,

This is an SVN patch request.

Type: Performance, no-brainer

Bugtracker references: http://bugs.typo3.org/view.php?id=15196

Branches: trunk


Problem:
t3lib_cache_backend_DbBackend::has($entryIdentifier) could be 50% faster 
using sql_num_rows instead of getRows/count

Cheers, Michael
