Very less CPU Usage and less QPS

Hi,

gqlgen version - v0.17.36
Pods - 10
CPU - 1
Mem - 1 GB

I am building an API server with Clickhouse database using gqlgen package.
The schema I am using just 2 and with straight 6 keys without any nested schema.
My API server deployed in kubernetes.

I am trying to hit around 50K QPS since I have 10 CPU cores running with big Clickhouse cluster running in background.
But I am able to hit only 5K QPS and my cpu usage is very less with just 1.5 but the average response time seems max 150ms.

I want to scale the system up to receive more QPS, I am not sure if I am missing something with http connections or need some special configurations.Also, I should be able to generate more QPS in future.

But my CPU is not at all utilising more than 10%, need some help to maximise the performance.
Thanks in advance!

该 issue 描述了一个基于 gqlgen、使用 Clickhouse 的 API 服务器存在 CPU 利用率和 QPS 偏低的问题。首先检查服务器的 HTTP 配置、连接池以及 gqlgen 执行设置。查找 GraphQL resolver 代码和数据库查询中的性能瓶颈。要确定根本原因，需要对应用程序进行性能分析并检查 Kubernetes 资源限制。
