Subject RE: [users@httpd] Serving and caching large static files
Date Tue, 22 Nov 2011 08:16:12 GMT
We're using disk cache.
We're working under the assumption that cache gives faster performance. The tests we performed
were not conclusive but we often got slightly better results when we used cache.

Is your suggestion not to use cache at all?

The "leak" I mentioned is not a real leak. When Apache serves a non-cached file that is about
to be cached, it first reads it in to memory. This causes the Apache process memory usage
to grow by the served file size. After the file is served the memory usage doesn't shrink
back.

Thanks,

What kind of caching?  What's the point in caching a static file
that's already on disk?  How do you measure the leak?
