The dataset is composed of 242944 requests. The dataset was shuffled in such a way that the different pages were visited in a random order, but requests seen on each page were replayed as they were recorded initially. This requests dataset was created using a pool of Chrome headless browsers (driven by the puppeteer library) to visit home pages of the top 500 domains (as reported by Cliqz Search), as well as up to 3 pages of each domain (picked randomly from the home page) and collecting all the network requests seen (URL, frame URL and type). We then analyzed the results in three different ways: all requests, blocked only and not blocked (taken from the same run). To measure the performance of each content-blocker, we replayed requests from popular domains once and kept track of the time it took to decide if they should be blocked or not.

The memory usage of Brave could not be evaluated using the devtools and thus is not included in this section.

8.8x less memory than DuckDuckGo's adblocker.

Memory Consumption of Ghostery's Blocking Engine (at startup, in Chrome): 1.8 MB

DuckDuckGo's adblocker does not offer serialization, so the loading cost is always the one from parsing the lists.

Loading Ghostery's Blocking Engine (from cache): 0.03 ms

1258.4x faster than DuckDuckGo's adblocker.

Time to Process a Request in Ghostery (median): 0.007 ms

All content-blockers except DuckDuckGo have sub-millisecond median decision time per request.

96 using the memory snapshot tool.īefore presenting the detailed analysis of the results, let us highlight our findings in a nutshell: Memory measurements were performed in Google Chrome version. The version of uBlock Origin running in this benchmark does not make use of the Webassembly version of domain matching.Īll benchmarks were ran on an X1 Carbon 2016 (i7 U6600 + 16 GB) in Node.js 11.9.0. To allow comparing uBlock Origin as well, we had to extract the static network filtering engine out of the extension. We leave this for future work.Īll blockers except uBlock Origin are available as JavaScript libraries which can be loaded in Node.js. We did not include native blockers from Chromium and Safari projects as this would require some significant effort to package them in a way that allows benchmarking against the other libraries. Here are the home pages for all content-blockers compared:

This comparison does not involve full extensions, but instead focuses on network request blocking engines, which is the most CPU intensive task performed by content-blockers (in particular, this does not account for cosmetics engines or subscription management).

Besides, efficiency is continuously improved and technologies such as WebAssembly will allow to go even further. We showed in another study The Tracker Tax that blocking ads and trackers actually reduces the loading time of websites by up to a factor of 2. Our comparison demonstrates that the most popular content-blockers are already very efficient (having a sub-millisecond median decision time per request) and should not result in any over-head noticeable by users. In this study, we show that the performance argument does not hold. The privacy argument deserves its own separate analysis and will not be covered here. Two justifications were put forth: one related to performance and another related to privacy. One of the proposed changes involves crippling the WebRequest APIs to limit their blocking abilities. This study was motivated by the recent Manifest V3 controversy. The error message 'anonymous function' seems to be especially hard to search for, even within GTM and other Google support documentation.Here we present a detailed analysis of the performance of some of the most popular content-blocker engines: uBlock Origin, Adblock Plus, Brave, DuckDuckGo and Cliqz/Ghostery's advanced adblocker (shipped since Ghostery 8), which we will refer to as Ghostery for the rest of the article.

I've been googling like crazy to try to figure this out, but I'm out of my depth for a lot of this.

However, GTM is no longer loading, my Javascript isn't loading, and the error code is not very helpful. I have installed Google Tag Manager on my website, and am using it to load some Javascript onto my site.
