TPCC testing takes too much time

[ZhenlanJi]

I am new to k8s and TiDB. Now I have a confusing problem. I used kind to create a local k8s cluster with the following configure,

# three node (two workers) cluster config
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker

and followed this tutorial to deploy TiDB.

Afterward, I tried to run TPCC on the abovementioned TiDB cluster. However, this command tiup bench tpcc -H 127.0.0.1 -P 14000 -D tpcc --warehouses 10 -T 4 run has taken more than three days. Until now, it hasn't finished.

So, is this normal or did something go wrong? Can I do something to improve the efficiency of my TiDB cluster?
