What does below parsing, processing output mean?

Ya, I mean it took 1.2 second to parse, process and encode.

That is very very slow for query like this -

{
	answers(func: eq(PostType, "answer")) @filter(uid_in(ParentID, 0x9)) {
		uid
		expand(_all_) {
			uid
			Title
   		    Name
   		    AvatarURL
		}
	}
}

which output 11 posts of answer type and 1 post of question type and 12 associated users for each post in 1.2 second, I mean mysql does much much faster than that.
