Really slow benchmark, am I wrong?

Why is asaskevich/govalidator so much slower in the below code? Am I wrong?

package main

import (
    "fmt"
    "time"

    "github.com/asaskevich/govalidator"
    "github.com/go-playground/validator/v10"
)

// User contains user information
type User struct {
    FirstName string `valid:"required" validate:"required"`
    LastName  string `valid:"required" validate:"required"`
    Age       int32  `valid:"range(0|130)" validate:"gte=0,lte=130"`
    Email     string `valid:"required,email" validate:"required,email"`
    Street    string `valid:"required" validate:"required"`
    City      string `valid:"required" validate:"required"`
    Planet    string `valid:"required" validate:"required"`
    Phone     string `valid:"required" validate:"required"`
}

var validate *validator.Validate

const iterations = 10000

func main() {
    validate = validator.New()

    user := &User{
        FirstName: "Badger",
        LastName:  "Smith",
        Age:       80,
        City:      "string",
        Email:     "Badger.Smith@gmail.com",
        Street:    "Eavesdown Docks",
        Planet:    "Persphone",
        Phone:     "none",
    }

    println("govalidator.Struct (asaskevich):")
    before := time.Now()
    for i := 0; i < iterations; i++ {
        govalidator.ValidateStruct(user)
    }
    fmt.Println(time.Since(before))

    println("validate.Struct (go-playground):")
    before = time.Now()
    for i := 0; i < iterations; i++ {
        validate.Struct(user)
    }
    fmt.Println(time.Since(before))
}

Result:

govalidator.Struct (asaskevich):
135.03ms
validate.Struct (go-playground):
17.9687ms
