# 环境

ELK 5  
机器性能:  
4核/16GB/SSD硬盘

#问题1: Elasticsearch单节点写入速度(并发量)多少算是正常的?

我先把日志写到redis, 再用logstash转存到Elasticsearch, 并发量大概在1500-2000每秒的样子, 感觉单节点的Elasticsearch支持的并发量并不是很大, 这样是正常的么?

#问题2: 另外, 如果我要提升写入Elastic的性能, 是否只能用集群的方式呢?

比如说我想达到 4000/s 并发量, 我就只能网Elastic集群中加机器么?

你说的写入速度是每秒索引数吧，这个和并发是两码事。  
看你的配置这个应该算比较低，还有很多提升空间。  
具体优化还看瓶颈在哪里啦，先使用Monitoring监控起Elasticsearch集群的运行情况，找到瓶颈然后优化。
