对比了一下两个节点的服务器硬件,供大家参考
青岛节点
CPU:
Intel(R) Xeon(R) CPU E5-2430 0 @ 2.20GHz
硬盘:
/dev/xvda:
Timing cached reads: 15256 MB in 2.00 seconds = 7636.09 MB/sec
Timing buffered disk reads: 252 MB in 3.02 seconds = 83.54 MB/sec
网络:
ping baidu 17.0 ms
ping 19lou 15.3 ms
杭州节点
CPU:
Intel(R) Xeon(R) CPU E5645 @ 2.40GHz
硬盘:
/dev/xvda:
Timing cached reads: 12824 MB in 2.00 seconds = 6417.38 MB/sec
Timing buffered disk reads: 218 MB in 3.04 seconds = 71.63 MB/sec
网络:
ping baidu 33.3 ms
ping 19lou 3.4 ms
总结
青岛节点CPU和硬盘性能更高。
青岛节点连网通网络更快,杭州节点连电信网络更快。如果同时考虑电信和网通用户的访问,青岛节点更均衡。
