There are a lot of ways to manage this problem. My preferred path is to wrap interpolated fields with HttpUtility.UrlEncode() when I know a user can touch it and there are plausible reasons for allowing 'illegal' characters at form submit time.
In terms of performance, it is definitely faster. The amount of time it takes to render these partials is negligible. You'd have to switch up your tooling to measure things in microseconds instead of milliseconds if you wanted any meaningful signal.
