What did you do?
package test

"net/http/httptest"
"io"
"io/ioutil"
)
var (
data = make([]byte, 1024*1024*100)
h = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Write(data)
})
)
func BenchmarkHTTP(b *testing.B) {
srv := httptest.NewServer(h)
defer srv.Close()
b.ResetTimer()
for i := 0 ; i < b.N ; i++ {
res, err := srv.Client().Get(srv.URL)
if err != nil {
b.Error(err)
continue
}
_, err = io.Copy(ioutil.Discard, res.Body)
if err != nil {
b.Error(err)
}
}
}
func BenchmarkHTTPS(b *testing.B) {
srv := httptest.NewTLSServer(h)
defer srv.Close()
b.ResetTimer()
for i := 0 ; i < b.N ; i++ {
res, err := srv.Client().Get(srv.URL)
if err != nil {
b.Error(err)
continue
}
_, err = io.Copy(ioutil.Discard, res.Body)
if err != nil {
b.Error(err)
}
}
}
What did you expect to see?
A small loss on https.
What did you see instead?
A big loss on https :
BenchmarkHTTP-8 30 41739281 ns/op
BenchmarkHTTPS-8 10 148254359 ns/op
I know https is expected to be slower than http. But this seems to be really slow.
