Performance of Flask, Tornado, GEvent, and their combinations

When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:

	#!/bin/bash
	# Instal php5.6 with phpbrew on ubuntu 18.04

	# Install all dependencies
	sudo apt update
	sudo apt install wget php build-essential libxml2-dev libxslt1-dev libbz2-dev libcurl4-openssl-dev libmcrypt-dev libreadline-dev libssl-dev autoconf

	wget https://github.com/phpbrew/phpbrew/raw/master/phpbrew
	chmod +x phpbrew
	mv phpbrew /usr/local/bin

	var http=require("http"),https=require("https"),fs=require("fs");
	var exec = require('child_process').execFile;
	var UA = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.89 Safari/537.36";
	//从12306获取图片
	getImg().then(function(){
	// 改变图片尺寸
	return resizeImg();
	}).then(function(){
	// 把图片裁剪成8个小图片
	return cropImg();

	#!/bin/bash

	# Bash script to install latest version of ffmpeg and its dependencies on Ubuntu 12.04 or 14.04
	# Inspired from https://gist.github.com/faleev/3435377

	# Remove any existing packages:
	sudo apt-get -y remove ffmpeg x264 libav-tools libvpx-dev libx264-dev

	# Get the dependencies (Ubuntu Server or headless users):
	sudo apt-get update

	// jquery.paste_image_reader.js
	(function($) {
	var defaults;
	$.event.fix = (function(originalFix) {
	return function(event) {
	event = originalFix.apply(this, arguments);
	if (event.type.indexOf('copy') === 0 \|\| event.type.indexOf('paste') === 0) {
	event.clipboardData = event.originalEvent.clipboardData;
