Test Environment

Redis instance specifications
Redis 4.0 or 5.0 | 32 GB | Redis Cluster
ECS flavors
General computing-enhanced | c6.xlarge.2 | 4 vCPUs | 8 GB
Test tool
Three ECSs are used for concurrent tests. The test tool is memtier_benchmark.

Test Command

memtier_benchmark --cluster-mode --ratio=(1:0 and 0:1) -s {IP} -n {nreqs}  -c {connect_number}  -t 4 -d {datasize}

Reference values: -c {connect_number}: 1000; -n {nreqs}: 10,000,000; -d {datasize}: 32

Test Result

NOTE:

The following test results are for reference only. The performance may vary depending on the site environment and network fluctuation.
QPS: Query per second, indicates number of read and write operations per second. Unit: count/second.
Average Latency: Average latency of operations, in milliseconds.
x^th Percentile Latency: latency of x% of operations, in milliseconds. For example, if the value is 10 ms, 99.99^th percentile latency indicates that 99.99% queries can be processed within 10 ms.

**Table 1** Test result of running the SET command
