Made a direct comparison between my WiFi ISP provided router, my SBC PiHole WiFi Linux Router (running ethernet from ISP router), and cellular data only.
All speed tests were performed on my Pinephone in the same placement/location.
Needless to say I am a bit surprised by the results. I understand Pihole improves the speed of browsing by blocking various ad/data collectors, but still, had not expected this much improvement (given Pihole router feeds off the ISP router).
Here are some screenshots:

Found the vast difference interesting and wanted to share. Hope you find useful. Cheers until next time! :)
