I'd do the install (and uninstall) while taking a log to identify where the time is going. It's probably a costing or validation, but without data it's just guesswork.
1. What's that saying? "More computing sins have been committed for the sake of performance than anything else". You shouldn't be giving up a good component rule to make the install faster. However if you have a huge number of data files it might help to have some number of them in a single component with a versioned binary as its keypath that the data files use as a companion file for versioning. You get better control over versioning of the data files, and there's only one component for MSI to manage instead of one per data file. 2. This is the kind of thing you can do yourself and time it. 3. File hashing is a CRC of a kind, but again, you don't want to turn off file hashing because of the issues you'll get as a result. The other CRC, MSICHECKCRCS, is not set by default anyway. DISABLEROLLBACK might be an option, but again, bad things can result from using it.

Hello everybody, Thank you very much for your advices. I tried several options but an issue still remains. I was wondering if changing the way I organize components and media can affect install speed. What will perform faster: 1. Having 1 component per file, or putting large number of files in a single component 2. Providing I install from DVD what is faster : uncompressed files or cab . Note that big chunk of input files is already compressed. 3. Is there any overhead like CRC computation, or anything like performed at "File Copy" stage that I could switch off.
