718url = 'http://www.163.com'
t5 = time.time()
httplib2.Http().request(url)
t6 = time.time()
http2 = t6-t5
t3 = time.time()
req = httplib.HTTPConnection('www.163.com')
req.request('GET', '/')
t4 = time.time()
http = t4-t3
t1 = time.time()
urllib2.urlopen(url)
t2 = time.time()
urll = t2-t1
print http2
print http
print urll
结果：
0.156999826431
0.0150001049042
0.0780000686646
我写了如上代码测试的时候通常都是httplib的速度较快.实际过程中也是如此吗？还是我测试的不对。还有head请求与get请求，为什么head请求测试的时候感觉并没有节省时间呢。我想写爬虫程序，希望速度能更快。
