CPU restriction to 1 #226

Open cten opened 3 years ago

cten commented 3 years ago

We use this as a library in an application of ours, but we have found that the process never uses more than 1 CPU and will start to throttle new connections when the app gets close to using 1 CPU. Any help configuring the app to use more than a single CPU appreciated.

Hello, there are no CPU restrictions and it does not throttle. All scheduling is done by the Go runtime. Most likely, it sounds like your storage is slow and cannot keep up. To confirm, you can use the iostat command and check the await column See https://coderwall.com/p/utc42q/understanding-iostat
