Hello

How can i debug why NetXms Management Console is starting up really slow? Currently timed startup time to 3min and 53s. Most of that time was spent on "Synchronizing objects...".

Version is 3.8.382
DB is Ms Sql 2019

Was is faster of previous versions? What is the network throughput and ping time between nxmc machine and the server?

It seems to have gotten slower with addition of new nodes over time.

Server is in same machine as sql. Client is connected with 1g link and ping time is ~1ms.

It seems restarting the server + changing "ThreadPool.Poller.MaxSize" from 250->1200, "ThreadPool.Poller.BaseSize" 10->600 helped, now it loads in few seconds.

That's a great finding. The reason is that pollers can lock objects in some situations. Increasing the number of pollers reduces the chance that a locked objects would be encountered when nxmc is syncing objects.
