 3. **Optimizing JIT** (Ion/TurboFan): Takes frequently run code and aggressively optimizes it based on assumptions (e.g., "this variable is always an integer"). This is where the massive speed gains come from, but the complex logic required to guess and optimize creates a massive "attack surface" for exploits. Roughly half [1](https://microsoftedge.github.io/edgevr/posts/Super-Duper-Secure-Mode/#:~:text=roughly%2045%25%20of%20CVEs%20issued%20for%20V8%20were%20related%20to%20the%20JIT%20engine) [2](https://security.googleblog.com/2025/07/advancing-protection-in-chrome-on.html#:~:text=Of%20all%20the%20patched%20security%20bugs%20in%20V8%20with%20known%20exploitation%2C%20disabling%20the%20optimizers%20would%20have%20mitigated%20~50%25) of V8 engine vulnerabilities are found in this [optimizing tier](https://www.zellic.io/blog/pwning-v8ctf/#v8-and-just-in-time-compilation).
 
 #### Disable JIT optimization
-When you disable [V8 Optimization](https://www.youtube.com/watch?v=i7qlZeDt9o4) in Chrome, you are disabling Maglev (mid-tier optimizing compiler) and Turbofan (top-tier optimizer), but keeping Sparkplug (baseline compiler) and Ignition (interpreter).

 With modern CPUs and typical sites, you’ll rarely notice; some workloads may even be faster when avoiding JIT overhead for simple scripts. You won't notice any speed downsides and will have much better security without breaking most websites.
