It's very likely that your cache does not work at all :) Please ensure
that the cache hit rate on your side is not zero :)

The following slide shows how ngx_srcache + ngx_memc performs on
Amazon EC2's standard *Small* instance for caching small resultsets (a
single-line resultset) from a MySQL custom cluster:

http://agentzh.org/misc/slides/libdrizzle-lua-nginx/#84

And below is the result for caching big resultsets (100KB) in exactly
the same setup:

http://agentzh.org/misc/slides/libdrizzle-lua-nginx/#85

You can walk through all the remaining slides in the same place to
learn more about ngx_srcache and ngx_memc in your web browser by using
the pagedown/pageup keys on your keyboard.
