json,serialize,msgpack比較

速度

在redis中存入同樣的壓縮資料，取操作執行兩個操作：

1 從redis中取

2 解壓

3 統一json壓縮後放出

ab測試:

[yejianfeng@openstack ~/httpd/usr/bin]$ ./ab -n 10000 -c 10 'http://10.16.15.118:7701/location/testget?type=json'

壓縮比例：

[yejianfeng@test34x-nova /tmp]$ ll -h test* 

-rw-r--r-- 1 server server 29k jan  3 21:40 testjson 

-rw-r--r-- 1 server server 22k jan  3 21:40 testmsgpack 

-rw-r--r-- 1 server server 31k jan  3 21:40 testserialize

[yejianfeng@test34x-nova /tmp]$ ll test*    

-rw-r--r-- 1 server server 28942 jan  3 21:40 testjson 

-rw-r--r-- 1 server server 21993 jan  3 21:40 testmsgpack 

-rw-r--r-- 1 server server 31537 jan  3 21:40 testserialize

msgpack是serizalize的69%

json是serizalize的91.8%
