Trust me guys. Nginx can never be memory efficient.
Interesting way to start an email.
I never understand for what reason it creates a garbage of disk cache for
every request.
By default nginx doesn’t cache anything the OS/Linux does it to reduce the
diskreads. You can adjust it by tuning the 'vm.pagecache' and related sysctl
variables.
look at the pic http://i.imgur.com/pD7rEDe.png
The pic doesn’t show anything specific to nginx except that you have 32 Gb
of ram of what ~23 Gb are free ~7.7Gb are linux filesystem cache and
something like ~2GB is used for apps etc.
If any of you have any suggestion to tweak nginx config. Please tell me.
To see what actually consumes the ram whole processlist would be needed and
as people stated - also the output of nginx -V.
