As it says on the Nginx docs for limit_req

One megabyte zone can keep about 16 thousand 64-byte states or about 8
thousand 128-byte states. 

What can a 100m zone for the fastcgi_cache store ?

depending on the length of the fastcgi_cache_key and how many variables that
contains i am sure could affect it but be nice to have a example for better
understanding of how many file paths are expected to be in the 100mb zone.
