python的三种url库性能与效率分析

还没开始整理的一些原始数据，先保留原始数据，回头再分析。

 

测试三种类型的python url库：

#coding:utf-8 ''' Created on Mar 7, 2011 @author: fore ''' import sys import pycurl import StringIO import urllib2 import urllib3 def f(url): c = pycurl.Curl() c.setopt(pycurl.URL, url) b = StringIO.StringIO() c.setopt(pycurl.WRITEFUNCTION, b.write) c.setopt(pycurl.FOLLOWLOCATION, 1) c.setopt(pycurl.MAXREDIRS, 5) c.perform() return b.getvalue() def l2(url): return urllib2.urlopen(url).read() def l3(url): httppool = urllib3.connection_from_url(url) response = httppool.get_url(url) return response.data # print '' def funcall(func): import time n = time.time() for i in xrange(1): value = func('http://10.20.187.231/') # print '.' # print value return time.time() - n #print 'pycurl', funcall(f) print 'urllib2', funcall(l2) #print 'urllib3', funcall(l3)

 

ps aux | grep pycurltest | grep -v grep | awk '{print $2}' | xargs strace -p

 

strace，看看各个库的实现做了哪些系统调用：
