Compiler mode=aggressive, any hidden traps?

I have to parse very large XML-Files. The Xojo performance (compiler option=aggessive) is pretty good. Parsing speed with Xojo 3.5GB/min. (Query speed with grep: 16GB/min., awk: 1GB/min.).

Are there any hidden traps with this compiler option?

How do you process your XML? With the XML classes in Xojo?

I created my own class with one monolitic parse method. Monolitic because 20% faster as Method with many funktion calls.

The main thing to be aware of is that build times could be much longer than Default, especially if you have any very long methods.
