This topic describes the performance test results of ApsaraDB for MongoDB instances at different read/write ratios.
Metrics
- Count: the sum of the recordcount value and the operationcount value. The recordcount parameter indicates the number of existing records. The operationcount parameter indicates the number of the operations to be executed.
- Threads: the number of threads that are used for the client test.
Note Four Elastic Compute Service (ECS) instances of 4 cores and 32 GB memory are used to evenly distribute threads for client concurrent testing.
- Throughput: the number of read and write operations. Unit: ops/s.
- RAL: the average latency of read operations. Unit: us.
- WAL: the average latency of write operations. Unit: us.
