Usually a small delay is inevitable with any browser. 3-5 actually isn't that bad but it also is dependent on the internet service you have.

As for the monitor hanging as it's coming up, are you putting the computer to sleep or just simply turning the monitor itself off?

It could be a Power Options setting that the HDD is going to sleep after a certain amount of time and thus causing it to appear that's hanging when it really isn't, it's just taking a minute to wake back up.
