Re: [WiX-users] Wix 3.5 performance

Thanks Rob - the -sval switch did the trick - clean checkout test ran in 68s.  I'll try this with wix3.5 on our master build tonight.

I'm sure there is a way to run the validation separately (i.e. outside of linking) - I'll check the documentation.
We'll want to run validation as a separate/asynchronous process that doesn't impact build timeframes.

Thanks again.
