JavaScriptJitAllowedForSites

Allow JavaScript to use JIT on these sites

Supported on:

  • Chrome (Windows) since version 93

Description:

Allows you to set a list of site url patterns that specify sites which are allowed to run JavaScript with JIT (Just In Time) compiler enabled.

Wildcards, *, are allowed.

JavaScript JIT policy exceptions will only be enforced at a site granularity (eTLD+1). A policy set for only subdomain.site.com will not correctly apply to site.com or subdomain.site.com since they both resolve to the same eTLD+1 (site.com) for which there is no policy. In this case, policy must be set on site.com to apply correctly for both site.com and subdomain.site.com.

This policy applies on a frame-by-frame basis and not based on top level origin url alone, so e.g. if site-one.com is listed in the JavaScriptJitAllowedForSites policy but site-one.com loads a frame containing site-two.com then site-one.com will have JavaScript JIT enabled, but site-two.com will use the policy from DefaultJavaScriptJitSetting, if set, or default to JavaScript JIT enabled.

If this policy is not set for a site then the policy from DefaultJavaScriptJitSetting applies to the site, if set, otherwise Javascript JIT is enabled for the site.

Supported features:

  • Applied to browser without restart. Note that some ongoing tasks may not be affected.
  • Applied at Samsung Browser profile level.
