performance.cache-size                  32MB
performance.cache-size                  128MB

I suspect these are for different translators and regretfully have the same name...
performance/io-cache and performance/quick-read.

# gluster volume get TEST0 all | grep features.ctime
features.ctime                          on
features.ctime                          on

Same - storage/posix and features/utime translators.
Yes, that's correct. These two xlators are dependent. Initially it was two different options to enable each xlators to enable ctime feature. 
The consumer had to enable both xlators with two different commands to enable ctime feature. So it was decided
to provide the same key "features.ctime" to enable both xlators internally resulting in two entries in volume info. 

Worth filing an issue about it, as it is indeed somewhat confusing.
