MongoDB vs TiDB vs CockroachDB benchmark

测试环境

cpu: Intel(R) Core(TM) i7-3610QM CPU @ 2.30GHz mem: 32GB os: Ferora Linux 24

安装和启动MongoDB

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.11.tgz tar zxvf mongodb-linux-x86_64-3.2.11.tgz mkdir db ./bin/mongod --path db

安装和启动TiDB

下载压缩包

wget http://download.pingcap.org/tidb-latest-linux-amd64.tar.gz wget http://download.pingcap.org/tidb-latest-linux-amd64.sha256

检查文件完整性，返回 ok 则正确

sha256sum -c tidb-latest-linux-amd64.sha256

解开压缩包

tar -xzf tidb-latest-linux-amd64.tar.gz cd tidb-latest-linux-amd64

./bin/tidb-server

安装和启动CockroachDB

wget https://binaries.cockroachdb.com/cockroach-latest.linux-amd64.tgz tar xfz cockroach-latest.linux-amd64.tgz cd cockroach-latest.linux-amd64 ./cockroach

结论： 1.MongoDB的写入性能还是远远高于NewSQL的，而且随着访问的增多，性能没有下降，反而请求少的时候没有完全发挥 2.TiDB的写入性能在前期要比CockroachDB，但是随着访问量的增多，性能下降明显，只有最初的一半，甚至低于CockroachDB 3.CockroachDB的性能虽然最差，但是非常平稳
