> methods like {{setDBProperty}} and {{getDBProperty}} work slow, if are used several times one after another. Example:
> {code:javascript}
> var a = this.getDBProperty('a');
> var b = this.getDBProperty('b');
> var c = this.getDBProperty('c');
> {code}
> Each getDBProperty-call does {{localStorage.getObject}} which may be slow if readable object is too big (it may take 100-150 ms). So, it's better to read list of values with one call, like:
> {code:javascript}
> this.getDBProperties(['a', 'b', 'c']);
> {code}
> And same for {{setDBProperties}}.
