    Yes centmin.sh menu option 4 to upgrade/downgrade Nginx is nice and fast :)

    What unused data you referring to ? the Nginx 1.7.9 source files ? All source files are at /svr-setup

    oh you mean memory usage not disk usage

    read Help! Linux ate my RAM!

    linux reports free mem and used memory different from windows.. linux uses free memory in cache which is freed when apps need memory for better performance

    use this command to read real free memory
    Code:
    free -m
    for instance here only 635MB is used really while 91+764 is free memory used in buffer/cache ready to be freed whenever apps need it
    Code:
    free -m
             total       used       free     shared    buffers     cached
Mem:          1504       1491         13          0         91        764
-/+ buffers/cache:        635        869
Swap:         2047          6       2041
