host server load and density with containers

I'm trying to evaluate the maximum capacity of my hosts so we plan next wave on hardware acquisitions.
we use containers only and need to know how many can we run on a single machine.

Is there any reference for pveperf to compare with?

I'm specifically interested in density and load. I know there's a lot of factors influencing load, but in my case IO isn't a problem as my DB and file servers are hosted separately.

currently my proxmox servers handle about 10 ct's on average. I know is low but I need specific data to give to my bosses.

thanks in advance
 
What kind of containers? If all containers are just idling and you have enough RAM you can have thousands of them per host. If you have a big database you might only be able to run one container on one host.

mostly web and java services (tomcat, jboss), nothing IO consuming. and containers are usually idle or with very low load.
