+# TiDB Sysbench Performance Test Report -- v5.1.0 vs. v5.0.2
+
+## Test overview
+
+This test aims at comparing the Sysbench performance of TiDB v5.1.0 and TiDB v5.0.2 in the Online Transactional Processing (OLTP) scenario. The results show that compared with v5.0.2, the Point Select performance of v5.1.0 is improved by 19.4%, and the performance of the Read Write and Update Index is slightly reduced.
+
+## Test environment (AWS EC2）

+
+### Software version
+
+| Service type   | Software version    |
+|:----------|:-----------|
+| PD        | v5.0.2 and v5.1.0   |
+| TiDB      | v5.0.2 and v5.1.0   |

+| Sysbench  | 1.0.20     |
+
+### Parameter configuration
+
+TiDB v5.1.0 and TiDB v5.0.2 use the same configuration.
+
+#### TiDB parameter configuration
+
+{{< copyable "" >}}
+
+```yaml
+log.level: "error"
+performance.max-procs: 20
+prepared-plan-cache.enabled: true
+tikv-client.max-batch-wait-time: 2000000
+```
+
+#### TiKV parameter configuration
+
+{{< copyable "" >}}
+
+```yaml
+storage.scheduler-worker-pool-size: 5
+raftstore.store-pool-size: 3
+raftstore.apply-pool-size: 3

+readpool.unified.max-thread-count: 20
+readpool.storage.normal-concurrency: 10
+pessimistic-txn.pipelined: true

+```
+
+#### TiDB global variable configuration
+
+{{< copyable "sql" >}}
+
+```sql
+set global tidb_hashagg_final_concurrency=1;
+set global tidb_hashagg_partial_concurrency=1;
+set global tidb_enable_async_commit = 1;
+set global tidb_enable_1pc = 1;
+set global tidb_guarantee_linearizability = 0;
+set global tidb_enable_clustered_index = 1; 
+```
+
+## Test plan
+
+1. Deploy TiDB v5.1.0 and v5.0.2 using TiUP.
+2. Use Sysbench to import 16 tables, each table with 10 million rows of data.
+3. Execute the `analyze table` statement on each table.
+4. Back up the data used for restore before different concurrency tests, which ensures data consistency for each test.
+5. Start the Sysbench client to perform the `point_select`, `read_write`, `update_index`, and `update_non_index` tests. Perform stress tests on TiDB via HAProxy. The test takes 5 minutes.
+6. After each type of test is completed, stop the cluster, overwrite the cluster with the backup data in step 4, and restart the cluster.
+
+### Prepare test data
+
+Execute the following command to prepare the test data:
+
+{{< copyable "shell-regular" >}}
+
+```bash
+sysbench oltp_common \
+    --threads=16 \
+    --rand-type=uniform \
+    --db-driver=mysql \
+    --mysql-db=sbtest \
+    --mysql-host=$aws_nlb_host \
+    --mysql-port=$aws_nlb_port \
+    --mysql-user=root \
+    --mysql-password=password \
+    prepare --tables=16 --table-size=10000000
+```
+
+### Perform the test
+
+Execute the following command to perform the test:
+
+{{< copyable "shell-regular" >}}
+
+```bash
+sysbench $testname \
+    --threads=$threads \
+    --time=300 \
+    --report-interval=1 \
+    --rand-type=uniform \
+    --db-driver=mysql \
+    --mysql-db=sbtest \
+    --mysql-host=$aws_nlb_host \
+    --mysql-port=$aws_nlb_port \
+    run --tables=16 --table-size=10000000
+```

+
+## Test plan
+
+1. Deploy TiDB v5.1.0 and v5.0.2 using TiUP.
+2. Create a database named `tpcc`: `create database tpcc;`.
+3. Use BenchmarkSQL to import the TPC-C 5000 Warehouse data: `tiup bench tpcc prepare --warehouse 5000 --db tpcc -H 127.0.0.1 -p 4000`.
+4. Execute the `tiup bench tpcc run -U root --db tpcc --host 127.0.0.1 --port 4000 --time 300s --warehouses 5000 --threads {{thread}}` command to perform stress tests on TiDB via HAProxy.
+5. Extract the tpmC data of New Order from the result.
+
+## Test result
+
+Compared with v5.0.2, the TPC-C performance of v5.1.0 is **improved by 2.8%**.
