[squid-dev] [PATCH] external_acl_type cache=n docs

[Alex Rousskov]

Hello,

     The attached patch changes external_acl_type cache=n documentation 
to better reflect the [ugly] reality. The patch does not change how the 
cache works, but may help admins configure the cache correctly if they 
stumble upon this documentation.

A typical external ACL cache with the default cache settings consumes 
about 70 MB of RAM (more in many cases, e.g., if annotations are used 
with external ACLs). Besides memory usage, the default cache is using 
only 977 hash buckets for 262144 entries so there may be quite a bit of 
linear search going on by default.

If you think the default limit should be changed, please say so or file 
a bug report, but this specific patch is about fixing documentation only.


HTH,

Alex.
