Issue Details

Steps to reproduce:

1. run the test https://browserbench.org/Speedometer3.0/ with version 5.0.57
2. run the test https://browserbench.org/Speedometer3.0/ with version 5.0.42 (or 49, not sure)

Expected Behavior

results should be the same

Actual Behavior

with the newer version results are poor (-25% in my case)

Screenshots

5.0.57


adguard disabled, performance similar to 5.0.42 (or 49, not sure)


ublock origin lite mv3 for comparison

@x-rated, hello! I don't see the difference either.

[x-rated]

i tried clean install of adguard with same settings, but still 25% lower 😐 can i download version 5.0.42 somewhere? 🤔

[alexx7311]

@x-rated Here's 5.0.43 https://uploads.adguard.org/chrome-mv3_v5.0.43-beta.zip and this is 5.0.49 https://uploads.adguard.org/chrome-mv3_v5.0.49-beta.zip

@alexx7311 thank you for sharing the links

for me last version without performance loss is 5.0.43 🤔 5.0.49 is already slow as 5.0.57 something definitelly went wrong there after 5.0.43 😐 my cpu is i9-9900K

5.0.43


5.0.49


i used these settings in all versions: {"protocol-version":"2.0","general-settings":{"allow-acceptable-ads":false,"show-blocked-ads-count":true,"autodetect-filters":true,"safebrowsing-enabled":false,"filters-update-period":-1,"appearance-theme":"system"},"extension-specific-settings":{"use-optimized-filters":false,"collect-hits-count":true,"show-context-menu":true,"show-info-about-adguard":false,"show-app-updated-info":true,"hide-rate-adguard":false,"user-rules-editor-wrap":false},"filters":{"enabled-filters":[2,3,4,5,11,17,18,19,20,21,22,105,208,255,256,257],"enabled-groups":[0,1,2,3,4,5,6,7],"custom-filters":[],"user-filter":{"enabled":true,"rules":"","disabled-rules":""},"allowlist":{"enabled":true,"inverted":false,"domains":[],"inverted-domains":[]}},"stealth":{"stealth-disable-stealth-mode":false,"stealth-hide-referrer":false,"stealth-hide-search-queries":true,"stealth-send-do-not-track":true,"stealth-block-webrtc":false,"stealth-remove-x-client":true,"stealth-block-third-party-cookies":true,"stealth-block-third-party-cookies-time":2880,"stealth-block-first-party-cookies":false,"stealth-block-first-party-cookies-time":4320,"block-known-trackers":true,"strip-tracking-parameters":true}}

with 5.0.49 and later i notice little lags during the test progress - always in first thirds of each segment 🤔 approximately marked in the screenshot bellow (except for the first segment which is always laggy even without adguard)

lags


[x-rated]

after a bit of testing, i managed to reach full score 20+ points in 5.0.57 😮 it has something to do with these settings 🤔

• allowlist
• user rules
• help with adguard filters development
• show the count on adguard icon
• add to context menu
• show warning about extension update

i had to turn all these switches off and restart the anonymous window i was testing in 🤔 but it is weird - when i turn off only couple of them, there was always same low score -25% 🤔

these are my new settings for better performance {"protocol-version":"2.0","general-settings":{"allow-acceptable-ads":false,"show-blocked-ads-count":false,"autodetect-filters":true,"safebrowsing-enabled":false,"filters-update-period":-1,"appearance-theme":"system"},"extension-specific-settings":{"use-optimized-filters":false,"collect-hits-count":false,"show-context-menu":false,"show-info-about-adguard":false,"show-app-updated-info":false,"hide-rate-adguard":false,"user-rules-editor-wrap":false},"filters":{"enabled-filters":[2,3,4,5,11,17,18,19,20,21,22,105,208,255,256,257],"enabled-groups":[0,1,2,3,4,5,6,7],"custom-filters":[],"user-filter":{"enabled":false,"rules":"","disabled-rules":""},"allowlist":{"enabled":false,"inverted":false,"domains":[],"inverted-domains":[]}},"stealth":{"stealth-disable-stealth-mode":false,"stealth-hide-referrer":false,"stealth-hide-search-queries":true,"stealth-send-do-not-track":true,"stealth-block-webrtc":false,"stealth-remove-x-client":true,"stealth-block-third-party-cookies":true,"stealth-block-third-party-cookies-time":2880,"stealth-block-first-party-cookies":false,"stealth-block-first-party-cookies-time":4320,"block-known-trackers":true,"strip-tracking-parameters":true}}

screen recordings from testing - you can notice that "bad score" video is twice longer + those lags in first thirds of segments at the bottom i mentioned earlier 🤔

• old settings bad score: https://www.youtube.com/watch?v=HIl4g8wZzRc
• new settings, good score: https://www.youtube.com/watch?v=va161D3Oruo

[maximtop]

probably it should be enough to disable only "help with adguard filters development" setting

[x-rated]

@maximtop thats it 😮 this is the only switch which slows down the performance after 5.0.43 ☠️ i didnt test all possible combinations before, just randomly these "for me not so important" features 😐

[maximtop]

@x-rated This is expected because it involves a resource-intensive operation. When this setting is enabled, the AdGuard script traverses all elements to determine which ones are being blocked, which can impact performance.
