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
