Test Data of Master/Standby DCS Redis 6.0 Instances

DCS Redis 6.0 basic edition instances support SSL. This section covers the performance tested with and without SSL enabled.

Test Environment

Redis instance specifications
Redis 6.0 | Basic edition | 8 GB | Master/Standby

Redis 6.0 | Basic edition | 32 GB | Master/Standby
ECS flavors
General compute-plus | 8 vCPUs | 16 GiB | c7.2xlarge.2
ECS image
Ubuntu 18.04 server 64-bit
Test tool
A single ECS is used for the test. The test tool is memtier_benchmark.

Test Command

SSL disabled:

./memtier_benchmark -s {IP} -p {port} -c {connect_number} -t {thread}  -n allkeys --key-prefix="xxxx" --key-minimum=1 --key-maximum={max_key} --key-pattern=P:P --ratio=1:0 -d {datasize}

Reference values: -c {connect_number}: 1000, --key-maximum{max_key}: 2000000, -d {datasize}: 32

SSL enabled:

./memtier_benchmark -s {IP} -p {port} -c {connect_number} -t {thread}  -n allkeys --key-prefix="xxxx" --key-minimum=1 --key-maximum={max_key} --key-pattern=P:P --ratio=1:0 -d {datasize}  --tls --cacert ca.crt

Reference values: -c {connect_number}: 1000, --key-maximum{max_key}: 2000000, -d {datasize}: 32

Test Result

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.
