RedisVsEtsShowdown

Benchmark Redis vs ets for simple key value stuff

How to use

# tweak vars in lib/bench.exs and run it
mix run lib/bench.exs

Quick explanation of names

ets_get_1000: does an ets lookup 1000 times

redis_get_1000: does a redis lookup 1000 times using HGET

ets_get_multi: does an ets lookup 1000 times

redis_get_multi: does a single HMGET Redis lookup
