The value I specify for the size of my key zone in the proxy\_path  
statement

- is that a per-worker memory allocation or a shared memory zone? (i.e.  
if  
its 64mb and I have 32 processors, does the zone consume 64mb of main  
memory or 2gb?)

I suppose you are talking about the proxy\_cache\_path directive. Its docs  
[http://nginx.org/en/docs/http/ngx\_http\_proxy\_module.html#proxy\_cache\_path](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_path)  
state you are defining the size of a _shared memory zone_, most probably  
allocated by the master process at configuration loading time and then  
accessible/accessed by workers when needed.

## You will be able to make a conclusion by yourself. :o)
