mongdb性能压力测试，随机查询，数据量1亿条记录

操作系统centos6.4x64位

从测试结果看，当mongodb将数据全部载入到内存后，查询速度根据文档的大小，性能瓶颈通常会是在网络流量和CPU的处理性能（该次测试中当数据全部在内存后，纯粹的查询速度可以稳定在10W/S左右，系统load可以维持在1以下，由于此时CPU已经被使用到极限了，当并发再大时load值会直线飙升，性能急剧下降）。

压力生成服务器与Mongodb服务器基本配置

cpu型号：Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz

内存：64G

硬盘：10K转速 6块做RAID0，raid卡cache 1G（磁盘的IO性能决定MONGODB将非热点数据载入到内存的速度，当热点数据全部在内存后，IO性能可以忽略）

网卡速度：接入千兆交互机，速度1000MB

数据结构，user_id为索引键值为0-99999999，数据总大小约37G左右，全部载入内存后约32G

}

压力生成脚本开启40个进程，并发随机查询

[root@mdb-166 app]# cat mselectmongodb.py

import time,pymongo,multiprocessing,random,string

class SqlToMongo:

def m_sql(self,x,y):

server="mongodb://python:oracle@192.168.4.167:27017/syslog"

conn=pymongo.Connection(server)

db=conn.syslog

col=db.thing

start=x*y

end=start+x

for i in xrange(start,end):

d=random.randint(start,end)

val=col.find({"user_id":d})

a=list(val)

def gen_load(x,taskid):

task=SqlToMongo()

print "task %s start!" % taskid

task.m_sql(x,taskid)

if __name__ == "__main__":

inser_number=2500000

pro_pool = multiprocessing.Pool(processes=101)

print time.strftime('%Y-%m-%d:%H-%M-%S',time.localtime(time.time()))

start_time=time.time()

manager = multiprocessing.Manager()

for i in xrange(40):

taskid=i

pro_pool.apply_async(gen_load,args=(inser_number,taskid))

pro_pool.close()

pro_pool.join()

elapsed = time.time()-start_time

print elapsed

time.sleep(1)

print "Sub-process(es) done."

压力生成服务器负载，同时开启80个并发时抗不住了
