Hi @aruneshdutta, welcome to the forum!

Emoncms is quite a lightweight application, it runs very well on a Raspberry Pi.

To properly answer this question we would need more info regarding how you plan to use Emoncms. Obviously more processing power, RAM and SSD are desirable if posting 1000’s of feeds with many users!

See the emoncms github read me requirements section for software package requirements: https://github.com/emoncms/emoncms#requirements

100 feeds It should work on with 1GB of ram. It runs great on a RasPi3 with 1GB RAM.

Emoncms is more of a disk I/O intensive application rather than RAM hungry. Using an SSD will result in better performance.

I would recommend using Redis and PHPFINA data storage engine. Would you agree @TrystanLea?

I hope @glyn.hudson you have found the message directed to the automated reply for post approval,I expect things to be normal as before as this delays information and is not expected for such open source solution

Yes I have SSD on run I’ll use the same

Apologies for the automated temporary block. This should now have been removed.

I run mine in a VM on an HP Micro server under Exsi with about 4 other VMs. VM base OS is DietPi (plus I use Lighttpd) and I think it is about 700Mb allocated memory. Never uses it all but only about 25 feeds.

Also depends if you are running other services or applications such as node-red and mosquitto on the same server. Just EmonCMS should be fine.
