With Visual Build, you can run parts of build process in parallel (see the last part of
http://www.kinook.com/VisBuildPro/Ma...hainsample.htm). That may or may not actually make the build faster, depending on CPU usage, hard drive contention, etc.
As far as creating and managing builds, using Visual Build should definitely be much more productive than using batch files and AutoIT alone (see
http://www.kinook.com/VisBuildPro/features.html).
You can watch the
tutorials to get an idea of how Visual Build can help with the build process. The
help and
samples also provide a wealth of information for incorporating Visual Build into your build process.
