MongoDB性能测试与Python测试代码

下面是对mongodb测试的代码和结果。虽然公司用的一水的CentOS，但是由于我是FreeBSD的支持者，所以在FreeBSD和CentOS上都测试了一

#!/usr/bin/env python

from pymongo import Connection
import time,datetime

connection = Connection('127.0.0.1', 27017)
db = connection['hawaii']

def func_time(func):
        def _wrapper(*args,**kwargs):
                start = time.time()
                func(*args,**kwargs)
                print func.__name__,'run:',time.time()-start
        return _wrapper

@func_time
def remove():
        posts = db.userinfo
        print 'count before remove:',posts.count();
        posts.remove({});
        print 'count after remove:',posts.count();

if __name__ == "__main__":
        remove()
