If you don't want the default pool, just call Release()/ReleaseTimeout() to close it.

@panjf2000 can you update this example where it doesnt have any mem allocated when doing nothing?

package main

import (
        "time"
        "github.com/cloudxaas/gosysinfo/mem"   //go get -u github.com/cloudxaas/gosysinfo/mem@7a71da0

        "github.com/panjf2000/ants/v2"
)

func main() {

        ants.Submit(func() { //this doesnt work
                cxsysinfomem.LogMemStatsPeriodically(3 * time.Second)
        })

        select {}
}
