【内核参数】细分通用场景下的内核参数优化清单？

针对前、中、后端的业务请求数、数据处理类型、长短链接等方面，是有较大差异的，在网络参数上至少是可以形成不同的参数规范。
针对云底座、容器底座、裸金属、虚机等四个不同应用场景，在使用上存在较大差异，如云底座更关注云平台、硬件之间适配兼容，容器底座涉及防火墙配置也要求更加轻量化等，虚机相比物理机可使用的资源更少，故在部署上、参数模型方面应都有不同的规范。
针对计算密集型和大IO等类型，参数规范差异也很大，操作系统本身的调优场景（tuned）就支持性能吞吐模式（throughput-performance）和网络吞吐模式（network-throughput），可用的策略如下，供参考：
