-1. The `update.cmd` script NGens the compiler and libraries. This requires admin privileges.
 1. The compiler binaries produced are "private" and strong-named signed with a test key.
 1. Some additional tools are required to build the compiler, notably `fslex.exe`, `fsyacc.exe`, `FSharp.PowerPack.Build.Tasks.dll`, `FsSrGen.exe`, `FSharp.SRGen.Build.Tasks.dll`, and the other tools found in the `lkg` directory.

 * Making the tests run faster
-  * NGen-ing the F# bits (fsc, fsi, FSharp.Core, etc) will result in tests executing much faster. Make sure you run `src\update.cmd` with the `-ngen` flag before running tests.
   * The FSharp and FSharpQA suites will run test cases in parallel by default. You can comment out the relevant line (look for `PARALLEL_ARG`) to disable this.
   * By default, tests from the FSharpQA suite are run using a persistent, hosted version of the compiler. This speeds up test execution, as there is no need for the `fsc.exe` process to spin up repeatedly. To disable this, uncomment the relevant line (look for `HOSTED_COMPILER`).
