Title: Price of Portability
Post by: edbro on March 12, 2009, 08:06 AM

I use quite a few apps that come in regular or portable versions. Without regards to speed, I would think that a portable installation would always be preferable. So, should I assume that using the registry is faster than a portable config file? Why offer two versions of the same software if a portable install would do the trick?

Yes, I know that Firefox portable is designed to not use a cache. So, there is an example of an app that is better with a normal install. Any others?

The registry is safer than most standalone config systems, since writes are journalled. It's also faster, but that probably hasn't been relevant since the 80286 days (still gives a fuzzy feeling, though). It's not really hard supporting both registry and config-file support though, if you design your code properly and use a hierarchical/tree-structure configfile format like XML.

Offering two different versions shouldn't be necessary for most software, install-time (or even post-install) switching between regular and portable shouldn't be that difficult for a lot of stuff. Lots of application developers are either lazy or don't give much thought to this, though.
