bsmedberg informed me that caching results of code like Cc["@mozilla.org/file/directory_service;1"].getService(Ci.nsIProperties) is considered bad practice. However according to my measurements getService() takes > 0.3ms per invocation on N810(down from 0.6ms once bug 470859 is landed).
Seems that calling GetService from C++ is fast, but when called from JS the overhead of calling GetService is 10x greater that the call itself.

This is a profile of calling getService() in a loop.

When built with --with-kuser getService() overhead on n810 is similar to other xpconnect calls: 0.2ms
