I'm trying to setup elasticsearch cluster. I will get maximum of 4GB of data every day. So what will be hardware required to set up ElasticSearch 7.6.2 and kibana 7.6.2 What is ideal configuration for server- side RAM/Hard/disks/CPU. I currently have a single node cluster with: - Intel (R) Xeon (R) CPU E7- 4807 @ 1.87GHz CPU (s): 4 - 20GB RAM - 1TB HDD. As additional data, the logs will be collected by Decanter 2.0.0. Appreciate your help!! ---

Welcome to our community! 😃 If you are only using a single node cluster, that should be fine. But please use 7.7, it's the latest release 🙂 ---

Thank you very much for the welcome With the previous configuration it would be enough to index 4 GB daily without having any type of problem. How many documents per second should be indexed. Thank you so much. ---

How can I know how many documents per second my cluster is capable of indexing. ---

Ah ok, you will need to test that yourself as it's dependant on the hardware, use case etc 🙂 ---

For example I tried indexing 31000 documents in a java test that pulls in parallel with decanter logs to elasticsearch and I see that when finishing the elasticsearch test it continues indexing like 20 minutes later and it doesn't index me almost in real time as I expected, and I don't know what it is the problem, is it due to disk speed or do I have to have more hadware. ---

> [@eayala](#): > > it continues indexing like 20 minutes later and it doesn't index me almost in real time That's not how it works. As soon as your client has received a 200 response from Elasticsearch, then it's been indexed. What's happening after that might be merging, but it's hard to know without more information on what you are seeing. ---

My single node cluster has a shard with no replica, refresh\_interval: 30s was defined and each document is approximately 1 kb in size. ---

The first thing to check is that you have followed [these instructions](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-indexing-speed.html), especially about using bulk requests (especially since you are using HDD storage). Elasticsearch is often limited by disk utilization as indexing and associated merging can be very I/O intensive. ---

Thank you very much Christian\_Dahlqvist. I'm going to review those instructions. ---
