NetXMS Support Forum

As the subject asks, how many devices can NetXMS support before becoming unstable/slow?

It of course depends on the hardware resources your NetXMS server and your database server have available.
Database layer is the most taxed one (as is usual in applications like this), NetXMS server in itself doesnt require that much resources.

You will find plenty of 3k+ monitored node NetXMS deploys here on the forums.
There is no problem to support 10k monitored nodes or more tho.

Yes of course it's hardware based. There are systems out there that even though it says that it can support up to 10k devices; the system runs unstable at 5k devices (Cisco LMS for example). Anyways, thank you for the information.
