处理 20k rps 需要什么服务器配置？

最近压测了一下Hypercable Analytics，使用一台 8c32g 的 vultr 云服务，所有服务（ redis 、sidekiq 、rails 、openresty 、timescaledb ）在这台机器上，测试了一下从请求到入库的性能：

大概的处理结果是：

• 队列到插入数据库性能：2648 records/sec
• http 请求性能：6388 request/sec

如果把 sidekiq 关掉，单独测试 http 请求性能，大概可以处理 25k/s，就是说把每个服务单独部署的话，25k/s 算是 hypercable analytics 在 8c32g 单机处理的极限了。

所有服务都在容器内，可能直接放主机上的话，会稍微有些提升？
