How to set keys_zone for proxy_cache_path on linux

Thu Aug 2 10:09:07 UTC 2012

Hi,

I was wondering how to set the keys_zone parameter of the proxy_cache_path.

The wiki says
"Zone size should be set proportional to number of pages to cache. The 
size of the metadata for one page (file) depends on the OS; currently it 
is 64 bytes for FreeBSD/i386, and 128 bytes for FreeBSD/amd64. "

Are these numbers also true for linux? If not, what are they?
