tests for egw_cache_provider and not using APC for cli, if apc.enable_cli is not set
Also did some benchmarking on my Macbook (with a SSD and memcached running on localhost): Checking egw_cache_memcache: 0 checks failed, 100 iterations took 0.480 sec Checking egw_cache_apc: 0 checks failed, 100 iterations took 0.025 sec Checking egw_cache_files: 0 checks failed, 100 iterations took 0.826 sec --> APC is by a factor of 20 faster then memcached, which is double as fast compared to files on a SSD
