Concurrency test

[frg01]

I have qeustion baout concurrent，Is the concurrent benchmark test not supported yet? Because I don't seem to find that the database connection pool is used, but multi-threading is used. But why can the maximum number of multi-threaded connections be only 2? Have you considered adding a larger number of connections, or using some existing connection pooling tool?
The following is the relevant situation I encountered:
[INFO ] 2024-02-07 16:33:53,913 [main] com.oltpbenchmark.util.ThreadUtil runLoaderThreads - Creating a Thread Pool with a size of 2 to run 2 Loader Threads. 0 threads will be queued.
