MongoDB 1000W级数据 Insert和Query和Delete性能测试（分别测试 不加索引 和 加索引）

先看下测试机性能（64bit）：

测试程序：

#include <iostream>
#include <mongo/client/dbclient.h>
using namespace std;
using namespace mongo;

#define INIT_TIME \
struct timeval time1,time2; \

#define START_TIME \
gettimeofday(&time1,NULL); \

#define STOP_TIME \
gettimeofday(&time2,NULL); \

#define PRINT_TIME \
cout<<"Time:"<<time2.tv_sec-time1.tv_sec<<":"<<time2.tv_usec-time1.tv_usec<<endl;

int main() {
srand(time(NULL));
char ar[26+1];
DBClientConnection conn;
conn.connect("localhost");
cout<<"MongoDB Connected OK!"<<endl;
int count=10000000;
INIT_TIME;
START_TIME;
//insert
#if 1
while (count--) {
for (int i=0; i<26; i++) {
ar[i] = rand()%26+97;
}
ar[26]='\0';
BSONObj p = BSON("NewsId"<<ar);
conn.insert("test.users",p);
}
#endif

STOP_TIME;
PRINT_TIME;
return 0;
}

不加索引测试：

......................# MongoDB 不加索引 插入1000W条测试 #...................

^_^[root@:~/svn/nugget/MongoDB/utest]#./insertData
MongoDB Connected OK!
Time:207s:194125μs

......................# MongoDB 不加索引 1000W条遍历测试 #...................

我们让MongoDB全部遍历一遍：

让测试数据倒序，取倒序后第一条数据：

> db.users.find().sort({'_id':-1})
{ "_id" : ObjectId("4e2cbdf4a1ca039d82214e33"), "NewsId" : "dgvshdhevmjgunvbepgdkzirqk" }

第一条数据的NewsId为
dgvshdhevmjgunvbepgdkzirqk
测试程序：

^_^[root@:/usr/local/mongodb/bin]#./mongo<bat.js
MongoDB shell version: 1.8.2
connecting to: test
> var startTime = new Date();
>
> db.users.find({NewsId:"dgvshdhevmjgunvbepgdkzirqk"});
{ "_id" : ObjectId("4e2ccfd2a1ca039d82527b34"), "NewsId" : "dgvshdhevmjgunvbepgdkzirqk" }
>
> (new Date().getTime()-startTime.getTime())/1000
5.846s
> bye

......................# MongoDB 不加索引 1000W条删除测试 #...................

^_^[root@:/usr/local/mongodb/bin]#./mongo 10.7.3.228 < bat.js
MongoDB shell version: 1.8.2
connecting to: 10.7.3.228/test
> var startTime = new Date();
> //db.users.find({NewsId:"csgsqdglbyfuwdjfkkrxgzyacc"});
> db.users.remove()
> (new Date().getTime()-startTime.getTime())/1000
103.924
> bye

......................# MongoDB 不加索引 1000W条删除最后一条测试 #...................

^_^[root@:/usr/local/mongodb/bin]#./mongo 10.7.3.228 < bat.js
MongoDB shell version: 1.8.2
connecting to: 10.7.3.228/test
> var startTime = new Date();
> //db.users.find({NewsId:"csgsqdglbyfuwdjfkkrxgzyacc"});
> db.users.remove({"NewsId":"nmffcewwjvbhjfyagfxlifgiud"})
> (new Date().getTime()-startTime.getTime())/1000
3.991
> bye

加索引测试：

> db.users.getIndexes()
[
{
"name" : "_id_",
"ns" : "test.users",
"key" : {
"_id" : 1
},
"v" : 0
}
]
> db.users.ensureIndex({NewsId:1})
> db.users.getIndexes()
[
{
"name" : "_id_",
"ns" : "test.users",
"key" : {
"_id" : 1
},
"v" : 0
},
{
"_id" : ObjectId("4e2cc408572ff09d98851cb7"),
"ns" : "test.users",
"key" : {
"NewsId" : 1
},
"name" : "NewsId_1",
"v" : 0
}
]

还是一样取最后一条数据，然后看下性能：

^_^[root@:/usr/local/mongodb/bin]#./mongo <bat.js
MongoDB shell version: 1.8.2
connecting to: test
> var startTime = new Date();
>
> db.users.find({NewsId:"nxuvdqtjrrptoyildolesbkqmd"});
{ "_id" : ObjectId("4e2ccc2ea1ca039d82b9e4b3"), "NewsId" : "nxuvdqtjrrptoyildolesbkqmd" }
>
> (new Date().getTime()-startTime.getTime())/1000
0.022s
> bye
