[GitHub] [pulsar] BewareMyPower opened a new issue #10324: Inaccurate throughput statistics from pulsar-perf
BewareMyPower opened a new issue #10324:
URL: https://github.com/apache/pulsar/issues/10324
**Describe the bug**
When I run a pulsar-perf to produce messages to a single broker cluster with 100000 messages per second and the default 1KB message size, the throughput from client side is too large:
> 09:33:20.976 [main] INFO org.apache.pulsar.testclient.PerformanceProducer - Throughput produced: 100003.6 msg/s --- 781.3 Mbit/s --- failure 0.0 msg/s --- Latency: mean: 2.932 ms - med: 2.864 - 95pct: 3.593 - 99pct: 4.949 - 99.9pct: 27.037 - 99.99pct: 36.402 - Max: 36.464
> 09:33:31.005 [main] INFO org.apache.pulsar.testclient.PerformanceProducer - Throughput produced: 99998.4 msg/s --- 781.2 Mbit/s --- failure 0.0 msg/s --- Latency: mean: 2.806 ms - med: 2.839 - 95pct: 3.554 - 99pct: 3.704 - 99.9pct: 6.221 - 99.99pct: 15.474 - Max: 15.514
However, from the dashboard's metrics, the throughput is normal, which should be about 100000 / 1024 = 97.65 MB/s.
**To Reproduce**
Steps to reproduce the behavior:
1. Run a pulsar cluster or standalone
2. Run pulsar-perf
```bash
./bin/pulsar-perf produce -r 100000 my-topic
```
**Expected behavior**
The throughput should be accurate.

This is right.
Dashboard's unit is MB/s, PerformanceProducer's unit is Mbit/s.

@linlinnn Thanks, I just got used to MB/s.
