Content blockers in the same class as uBlock Origin ("uBO")[1] have the added burden of having to enforce generic filters which are independent of the request domains, they have to find a specific pattern in the request URL, including with support for wildcards.
Even though, and despite this added burden, I will point out that uBO is almost as performant as DDG Privacy Essentials as per this report.
Furthermore, uBO contains WASM modules but they are not used in the Chromium version of the extension since this would require to add a `wasm-eval` directive to uBO's extension manifest, something I prefer to avoid for the time being, I fear this would cause more lengthy validation of the extension by the Chrome Web Store.
