I've found it slower. I gave up on multiple monitors because I can't carry them around with me and many times I like to work away from the desk. As a result I'd find when I'm on the laptop, my work flow would deteriorate because I'm used to multiple windows rather than the alt tab sequence. So I made the decision to only use a 15" screen for everything, heavily depending on alt tab. As a result I've developed a muscle memory where there is zero thought alt tabbing to any window. This keeps my eyes in the same place - which decreases the tracking/fatigue involved and less context switch. However, using a second monitor does increase productivity when using a monitor behind the laptop for multiple log tails - mostly because 15" is not enough to show that data.
