<p>I run Flex Builder 3 on a mac and as my project grows - the compile time gets longer and longer and longer.  I am using some SWC's and there is a fair amount of code but it shouldn't take minutes to build and crash daily should it?</p>

You may want to explore the command-line compiler found in the Flex SDK,
```
mxmlc
```
. As I recall, Flex Builder 3 seems to hide all the compiler details, but perhaps there are arguments you can append that will help you speed up the compilation.
For example, you may want to set
```
optimize=false
```
which will skip the step of optimizing the bytecode (perhaps reducing compilation time)?  This of course comes at the price of performance and file size of the actual application.
More documentation on
```
mxmlc
```
can be found at:

.
Good luck!
