single core absolute fair environment less than 64k set get bench: redis overall performance faster than xredis 10 - 50% range qps （because of the memory management cost of using STL,the smaller the memory, the greater the gap） kernel bottleneck 80-90% cpu benchmark.pdf

cd xredis mkdir obj cd ./src/
make ./redis-server 0.0.0.0 6379 0 0 0

xredis is a compatible redis protocol with multithreaded client server
