Hi,

I recently just deployed ElasticSearch 5 on production (4 months ago). Our average document per day is around 5M. I index my document per day based on some datetime format. Initially it went just fine. But lately I noticed the Insert threshold getting slower. Please help, I'm already out of ideas. Below are some info related to my environment.

OS - Windows  
Current Storage Used - 300GB per node

**\_cluster/health**  
"cluster\_name" : "sds-escluster",  
"status" : "green",  
"timed\_out" : false,  
"number\_of\_nodes" : 2,  
"number\_of\_data\_nodes" : 2,  
"active\_primary\_shards" : 750,
