测试项目一：

CPU信息：

CPU核心数量的多少代表着你多线程运行的程序的快慢。当然性能不是绝对有优势的，看卖家把U平分到多少个人头上。不过一般来说U核心越多，性能越好。

[root@MyCloudServer ~]# cat /proc/cpuinfo

L5520的U性能不错，关键是给了3个核心。多线程运行效率会提升很多。

测试项目二：

空载内存信息：

内存是一个VPS最重要的部分之一。显然内存越大能够运行的程序越多，能够承载的访问量也越多。

[root@MyCloudServer ~]# free -m
total used free shared buffers cached
Mem: 1024 617 406 0 79 426
-/+ buffers/cache: 112 911
Swap: 255 0 255

空载时内存只用了57，系统优化不错。

硬盘：

[root@MyCloudServer ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
9.3G 1.4G 7.6G 15% /
/dev/xvda1 99M 36M 58M 39% /boot
tmpfs 513M 0 513M 0% /dev/shm

测试项目三：

硬盘IO测试：

DD测试硬盘

[root@MyCloudServer unixbench-5.1.3]# dd if=/dev/zero of=test bs=128k count=4k oflag=dsync
4096+0 records in
4096+0 records out
536870912 bytes (537 MB) copied, 4.45055 seconds, 121 MB/s
[root@MyCloudServer unixbench-5.1.3]# dd if=/dev/zero of=test bs=256k count=4k oflag=dsync
4096+0 records in
4096+0 records out
1073741824 bytes (1.1 GB) copied, 7.03131 seconds, 153 MB/s
[root@MyCloudServer unixbench-5.1.3]# dd if=/dev/zero of=test bs=256k count=4k oflag=dsync
4096+0 records in
4096+0 records out
1073741824 bytes (1.1 GB) copied, 6.65365 seconds, 161 MB/s

hdparm专用测试软件测试硬盘。

[root@MyCloudServer dev]# hdparm -t /dev/xvda

/dev/xvda:
Timing buffered disk reads: 1438 MB in 3.00 seconds = 478.83 MB/sec
[root@MyCloudServer dev]# hdparm -t /dev/xvda

/dev/xvda:
Timing buffered disk reads: 1516 MB in 3.01 seconds = 504.44 MB/sec

IO对于一个VPS来说也是非常重要的，数据都是存储在硬盘中的，如果硬盘的IO（读写）速度过慢，会导致VPS各种卡吨等现象。DD测试IO大于10M/S 做站无影响。

测试项目四：

端口速率：

IN速率：

[root@MyCloudServer ~]# wget http://cachefly.cachefly.net/100mb.test

IN的口子似乎没有多大的限制。

OUT速率：

日本数据中心测试下载速度。

50M的出口带宽在美国能跑这个速度还不错。

测试项目五：

Unixbench跑分:400以下为性能低下400-600正常水平，高于1K性能优异。
