Interested in a quick pick me up for performance and user experience within TBSM?
Consider this. The default Relationships View that is a core component of most TBSM deployments shows by default one level up and three levels down from the selected service instance. More often than not, the three levels down brings in a lot of child service instances in environments of any size. This results in longer model loading times and microscopic service models that force the use of zooming in to see what the model contains. Not an ideal user experience!
I think that this is one too many levels down and recommend that you change the defaults from three levels to two levels down. Take a look at this support tech note on how to change the defaults.
Give it a try and speak to your end users to see what they think!!!
