Why do my WP7 settings take so long to load?

I put a stopwatch on it. The first time the app loads (no settings file exists) it takes about 190ms to fail to load four settings. The app runs, three bools and a short string are written as settings, and the next time the app loads, it takes 400ms to read the first setting from the IsolatedStor开发者_JS百科ageSettings.ApplicationSettings collection and about 1ms to get the remainder.

Is there anything I can do to ameliorate this load time?

Ues a better Serialization method ;) XMLSerialization is okay for more complex graphs, but for simple settings, binary serialization would be much better. Also, when you say fail to load, I assume you're doing a check to see if the files exist? If not, I think there may be exceptions being thrown internally which would slow down execution as well.
