BC24 onPrem - Best practice for multiple instances on one server (instance settings)

(0) ShareShare

Posted on by 4
Hello,
 
for development- and data migration reasons we run multiple server VMs hosting multiple BC22/24-instances per VM. I want to keep the single BC instances as "lean" as possible (concerning RAM/io/network-usage), hence these instances are only used for data migrations processes and functionality tests and only by one user in parallel per instance. So there is no production use - only "pumping" data into the instance. Also i don't need all the services (ODATA, SOAP...) other then the access to web-client and developer services per instance.
 
When i create a new instance via powershell and just leave standard settings an have all the possible services activated, one instance "eats" like 4 GB of RAM or more, when started up. I remember older NAV-instances using only like max 1 GB per instance - or even less.
 
Long story short: Can you suggest any configuration parameter settings, or best practices that will impact the RAM usage and and performance of the instances.
 
Im aware, that i have to change the "CustomSettings.config", and i will obvisousely start by deactivating the unused services. Maybe somebody has done some "tuning" and can provide some good advice for this matter? 
 
Edit: There are roughly ~530 settings (including all kinds of cache-settings) in the CustomSettings.Config that might affect (or not)  the footprint of every single instance. So this question is basically about how to tweak these settings to get RAM/Resource-usage down and have more concurrent instances on one VM.
 
Thanks a lot, for sharing!

    @Khushbu Rajvi. Thanks for checking my question and adding a suggestion. We do already run multiple instances on one VM, so i will deactivate some of the unused services per instance. I was hoping to get more info on the parameter settings in CustomSettings.config - especially about the ones, that really impact RAM/resource-usage of the instance...
