I assume you've got the Source SDK (and that you're not running it through some sort of illegal means). So I guess that Hammer is a bit slow at compiling for you? If so, I highly suggest you take a look at
Nem's Site and hunt around for the Batch Compiler. It'll make life much easier!
Edit: Just read through your other thread. A note: when you compile a map, Hammer doesn't actually do anything. During the compile, 3 seperate programs are loaded, which do different things within your compile. You have vbsp.exe, which handles all the geometry, vvis.exe which handles the visualisation calculations and vrad.exe which handles the lighting calculations.
Using Nem's Batch Compiler will simply allow you to shut down Hammer to free up memory (Hammer tends to eat up a lot of memory during a compile). It also gives a nice however of the additional settings you can apply to the compiling programs.
