Using this verbosity level can be a useful way to check the effects of the growth factor used on slabs
with different memory allocations, which in turn can be used to better tune the growth factor to suit
the data you are storing in the cache. For example, if you set the growth factor to 4 (quadrupling the
size of each slab):
shell> memcached -f 4 -m 1g -vv
slab class 1: chunk size 80 perslab 13107
slab class 2: chunk size 320 perslab 3276
slab class 3: chunk size 1280 perslab 819
slab class 4: chunk size 5120 perslab 204
slab class 5: chunk size 20480 perslab 51
slab class 6: chunk size 81920 perslab 12
slab class 7: chunk size 327680 perslab 3
...
During use of the cache, this verbosity level also prints out detailed information on the storage
and recovery of keys and other information. An example of the output during a typical set/get and
increment/decrement operation is shown below.
