Performance Features Differences Releases

Chrome 155.0.0.0

no changes

Measured against the version before it on the same platform, OS and charset, across 18 vectors the network tested on this release.

← All releases

Nothing changed in Chrome 155.0.0.0 on the vectors the network ran. That is a result too — the browser behaved exactly as its predecessor did.
