简单的用 h2load测试了和nginx的http/2下的缓存性能，结果显示RPS（每秒请求数）nuster差不多是nginx的3倍

测试环境

服务器

两台linux服务器：一台测试服务器server129, 一台缓存服务器server130.

硬件

• Intel(R) Xeon(R) CPU X5650 @ 2.67GHz(12 cores)
• RAM 32GB
• 1Gbps ethernet card

软件

• CentOS: 7.4.1708 (Core)
• h2load: nghttp2/1.30.0
• nginx: nginx/1.14.0
• nuster: nuster/1.8.8.2
