1The test-lru.rb program can be used in order to check the behavior of the 2Redis approximated LRU algorithm against the theoretical output of true 3LRU algorithm. 4 5In order to use the program you need to recompile Redis setting the define 6REDIS_LRU_CLOCK_RESOLUTION to 1, by editing redis.h. 7This allows to execute the program in a fast way since the 1 ms resolution 8is enough for all the objects to have a different enough time stamp during 9the test. 10 11The program is executed like this: 12 13 ruby test-lru.rb > /tmp/lru.html 14
