I haven't found many discussions on mod_cache_socache topic.
httpd.apache.org documentation for CacheSocacheReadSize directive (mod_cache_socache) says:
| Quote: | "The CacheSocacheReadSize directive sets the minimum amount of data, in bytes, to be read from the backend before the data is sent to the client."
|
Whereas, enabled info_module explains it this way:
| Quote: | "CacheSocacheReadSize - The maximum quantity of data to attempt to read and cache in one go."
|
I can set my mind to understand that words 'minimum' and 'maximum' in the definitions above don't contradict each other, but still, I would like to clear my doubts...
Let's stick with the example given in the official documentation:
| Quote: | | CacheSocacheReadSize 102400 |
...which is 100kB.
Could somebody analyse how would cached documents/assets of http response have been handled if their size is either smaller or greater than 100kB?
Let's say...
A style.css is 8.5kB and script.js is 115 kB.
Can I say that style.css is going to be sent to the client in 1 go,
whereas script.js is going to be sent in 2 goes (100 + 15, perhaps)?
What performance consequences we can get if we set this value to 0.
What performance consequences we can get if we set this value to 1B.
What performance consequences we can get if we set this value to 100B and if the biggest cached document is 64kB, average is 20kB.
Thanks ahead... |
