If I split my cache like this: cache_dir aufs /usr/local/squid/small_obj 1700 16 256 max-size=800000 cache_dir aufs /usr/local/squid/big_obj 200 16 256 Presumably nothing bigger than max-size will end-up in the first cache, but how often will the smaller objects end-up in the second cache? Assuming that both cache-directories have filled.
The answer to this question depends heavily on how busy your cache is. The default store_dir_select_algorithm is "least-load". On a lightly used server, the first defined directory will be utilized the most. As the server is more heavily trafficed the other directories will be tapped more. Some discussion has passed about a min-size argument to cache_dir (to keep small objects out of the non-COSS cache_dirs), but I don't know where that led.
