Hello Jonathan, The MSO46 (and 4 Series MSO in general) has a different ARM processor than the 5 and 6 series MSOs. So the MSO46 doesn't perform as well, hence this is why you see the 4 series operate so slowly with a web interface like e*scope. Especially if the MSO46 is trying to run heavier processes while simultaneously managing network communications. Are you using the e*scope web interface with the MSO46 or are you using something else?
The 2-3 second lag is somewhat still longer than expected though. What does your setup look like? What are the settings and measurements on the MSO46 you are using? Do you have an IO trace (monitoring the communications)?
