This question may not have sufficient data to provide an accurate answer, but I'll settle for an approximate one. I'm planning to perform a lot of bulk inserts with node js elasticsearch, in chunks of 5MB. The ES is installed on a quad core, 8GB memory machine, and the script that runs the bulk inserts is located on another machine, but in the same VPN. I'm wondering what is the latency that I'm supposed to expect from each insert (50ms, 500ms, 50s?), since this value is important to ensure the proper flow of my script.
