这是python编写的用于测试网站访问速率的代码片段，可以输出打开某url的时间，访问100次的平均时间，最大时间和最小时间等等

import urllib2from datetime import * import timedef Process(url,n): minSpan = 10.0 maxSpan = 0.0 sumSpan= 0.0 over1s = 0 for i in range(n): startTime = datetime.now() try: res = urllib2.urlopen(url,timeout=10) except: pass endTime = datetime.now() span = (endTime-startTime).total_seconds() sumSpan = sumSpan + span if span < minSpan: minSpan = span if span > maxSpan: maxSpan = span #超过一秒的 if span>1: over1s=over1s + 1 print(u'%s Spent :%s seconds'%(url,span)) print(u'requested:%s times,Total Spent:%s seconds,avg:%s seconds, max:%s seconds,min:%s seconds,over 1 secnod:%s times'%(n,sumSpan,sumSpan/n,maxSpan,minSpan,over1s)) print('\n')if __name__=='__main__': Process('http:// Spent :0.031 secondsrequested:100 times,Total Spent:3.67 seconds,avg:0.0367 seconds, max:0.109 seconds,min:0.015 seconds,over 1 secnod:0 times
