How much extra memory for elastic search installatyin

[Mr Lucky]

I have Enhanced Search and I had elastic search installed on my server, but my hosting company is telling me I need to upgrade as elastic search requires a lot more memory.

Is this normal?

How much extra memory on the server should it need? (I currently have 3GB memory)

Thanks

I have about 1.5M posts and have dedicated 3GB for ElasticSearch.

Thanks. So if I have about 250,000 posts how much would you recommend?

1GB.

1GB is even too much, 512MB is enough.

Correct. But 1GB will allow for growth.

Sufficient Velocity works fine with Elastic Search using ~768mb with 3.2 million posts, and Space Battles does fine with 1536mb for ~16.7 million posts.

SSDs are awesome.

Correction. Looking at my current settings, I have 1GB set for ElasticSearch.
