##单线程测试代码:
## ben_singleton.rb
require 'benchmark'
require 'bigdecimal/math'
require 'rest-client'
require 'httparty'
require 'faraday'
require 'mechanize'
## 通过修改iterations控制请求数
iterations = 500
url = 'http://www.baidu.com/'
# 测试rest-client
Benchmark.bmbm(10) do |bm|
bm.report('rest-client') do
iterations.times do
response = RestClient.get url
end
end
end
# 测试httpary
Benchmark.bmbm(10) do |bm|
bm.report('httparty') do
iterations.times do
response = HTTParty.get(url)
end
end
end
## 测试faraday
Benchmark.bmbm(10) do |bm|
bm.report('faraday') do
iterations.times do
response = Faraday.get url
end
end
end
## 测试Mechanize
Benchmark.bmbm(10) do |bm|
bm.report('Mechanize') do
iterations.times do
response = Mechanize.new.get(url)
end
end
end
单线程测试结果:
循环次数10次,Mechanize速度最快:
