Test Data of Master/Standby DCS Redis 4.0 or 5.0 Instances

Test Environment

  • Redis instance specifications

    Redis 4.0 or 5.0 | 8 GB | master/standby

    Redis 4.0 or 5.0 | 32 GB | master/standby

  • ECS flavors

    General computing-enhanced | c6.2xlarge.2 | 8 vCPUs | 16 GB

  • ECS image

    Ubuntu 18.04 server 64-bit

  • Test tool

    A single ECS is used for the test. The test tool is redis-benchmark.

Test Command

redis-benchmark -h {IP} -p {Port} -a {password} -n {nreqs} -r {randomkeys} -c {connection} -d {datasize} -t {command}

Reference values: -c {connect_number}: 500; -n {nreqs}: 10,000,000; -r {randomkeys}: 1,000,000; -d {datasize}: 32; -t {command}: set
