It tracks recent evictions as +// well as recent usage in both the frequent and recent caches. Its +// computational overhead is comparable to TwoQueueCache, but the memory +// overhead is linear with the size of the cache. +// +// ARC has been patented by IBM, so do not use it if that is problematic for +// your program. +// +// All caches in this package take locks while operating, and are therefore +// thread-safe for consumers. +package lru |
