The default policy for cache replacement is LFUDA. Please see the type descriptions specified in the memory replacement policy for additional detail. select heap LFUDA Low-water-mark in % cache_swap_low Cache replacement begins when the swap usage is above the low-low-water mark and attempts to maintain utilisation near the low-water-mark. input 5 90 High-water-mark in % cache_swap_high As swap utilisation gets close to the high-water-mark object eviction becomes more aggressive. input 5 95 Do not cache donotcache Enter each domain or IP address on a new line that should never be cached. textarea 50 5 base64 Enable offline mode enable_offline Enable this option and the proxy server will never try to validate cached objects. The offline mode gives access to more cached information than the proposed feature would allow (stale cached versions, where the origin server should have been contacted). checkbox External Cache-Managers ext_cachemanager Enter the IPs for the external Cache Managers to be allowed here, separated by semi-colons (;). input 60 Squid Hard disk cacheSettings listtopic Hard disk cache size harddisk_cache_size This is the amount of disk space (in megabytes) to use for cached objects. input 10 100 Hard disk cache system harddisk_cache_system This specifies the kind of storage system to use. <p> <b> ufs </b> is the old well-known Squid storage format that has always been there. <p> <b> aufs </b> uses POSIX-threads to avoid blocking the main Squid process on disk-I/O. (Formerly known as async-io.) <p> <b> diskd </b> uses a separate process to avoid blocking the main Squid process on disk-I/O. <p> <b> null </b> Does not use any storage. Ideal for Embedded/NanoBSD. select ufs Level 1 subdirectories level1_subdirs Each level-1 directory contains 256 subdirectories, so a value of 256 level-1 directories will use a total of 65536 directories for the hard disk cache. This will significantly slow down the startup process of the proxy service, but can speed up the caching under certain conditions. select 16 Hard disk cache location harddisk_cache_location This is the directory where the cache will be stored. (note: do not end with a /). If you change this location, squid needs to make a new cache, this could take a while input 60 /var/squid/cache Minimum object size minimum_object_size Objects smaller than the size specified (in kilobytes) will not be saved on disk. The default value is 0, meaning there is no minimum. input 10 0 Maximum object size maximum_object_size Objects larger than the size specified (in kilobytes) will not be saved on disk. If you wish to increase speed more than you want to save bandwidth, this should be set to a low value. input 10 4 Squid Memory Cache Settings listtopic Memory cache size memory_cache_size This is the amount of physical RAM (in megabytes) to be used for negative cache and in-transit objects. This value should not exceed more than 50% of the installed RAM. The minimum value is 1MB. input 10 8 Maximum object size in RAM maximum_objsize_in_mem Objects smaller than the size specified (in kilobytes) will be saved in RAM. Default is 32. input 10 32 Memory replacement policy memory_replacement_policy The memory replacement policy determines which objects are purged from memory when space is needed. The default policy for memory replacement is GDSF. <p> <b> LRU: Last Recently Used Policy </b> - The LRU policies keep recently referenced objects. i.e., it replaces the object that has not been accessed for the longest time. <p> <b> Heap GDSF: Greedy-Dual Size Frequency </b> - The Heap GDSF policy optimizes object-hit rate by keeping smaller, popular objects in cache. It achieves a lower byte hit rate than LFUDA though, since it evicts larger (possibly popular) objects. <p> <b> Heap LFUDA: Least Frequently Used with Dynamic Aging </b> - The Heap LFUDA policy keeps popular objects in cache regardless of their size and thus optimizes byte hit rate at the expense of hit rate since one large, popular object will prevent many smaller, slightly less popular objects from being cached. <p> <b> Heap LRU: Last Recently Used </b> - Works like LRU, but uses a heap instead. <p> Note: If using the LFUDA replacement policy, the value of Maximum Object Size should be increased above its default of 12KB to maximize the potential byte hit rate improvement of LFUDA. select heap GDSF Dynamic and Update Content listtopic Cache Dynamic Content cache_dynamic_content enable caching of dynamic content.

Notes:
Squid wiki suggests 'Finish transfer if less than x KB remaining' on 'traffic mgmt' squid tab to -1 but you can apply your own values to control cache.

set Maximum download size on 'traffic mgmt' squid tab to a value that fits patters your are applying.
