Marketo has been fairly slow for us for several months now. I'm kind of curious if it has anything to do with the number of approved assets that we have (we leave them approved so they still show up in the analytics reports).
Until service impproves, I am no longer running reports or building SMs in front of an audience or our executives -- it's a very comforatble experience making conversation while the dots are spinning.
Overall slow marketo performance for me for some weeks now. Not sure if they are tips (see Allison J post) to make the tool quicker to user. This is really painful at times !
Our instance is constantly slow. Reports take a very long time to load and exporting lists take even longer. We have been experiencing this since the interface change (not sure if that has anything to do with it). We are constantly opening tickets. Hope it turns around soon.
