10 Minutes... is that all.
It looks like it is not responding.... but it is. It just needs to finish.
This is perfectly normal for a map with complex objects or large open spaces.
I did some tests, Dos Batch Compiling vs Hammer Expert.
The time saving on a 1.5 hour compile was about 8 minutes less for Batch with all tools run. That of course will depend on what programs your machine is running in the background when you compile with Hammer.
Batch is good for flexibility. But I didn't get Massive time savings as suggested by some. depends on your machine and operating system
If you are compiling in Expert mode and you don't want RAD to run, I am guessing you are just testing entities? Then just uncheck the box next to it. Might as well do VIS while your at it. This is the perfect way to test entity setups without waiting.
However R_speed readings will not be correct unless you compile fully with all the tools.
