Can the 4core 8G server, running rails service, support 5000-10000 concurrent requests?

Server configuration: 4core 8G

there are several nginx+rails+mongodb+redis+sidekiq services.

where rails starts 2 worker, and one worker10 thread
sidekiq concurrency is set to 15

how should I optimize or upgrade the server?


if you just return a hello world, you can multiply it by 10, and you don't need to optimize or upgrade.
