    Reduced @nextjs publish times by 80% last night (over 1 hour to now 15 minutes). Using @rustlang more has increased publish times. We started using @vercel Remote Cache + @turborepo for reliable, consistent cache hits. Expect even more frequent Next.js canaries!
    Line chart showing Next.js publish times reducing from an average of 75 minutes to 15 minutes after leveraging Turborepo and Vercel Remote Cache

    Replying to @rahul3103 @nodejs and 3 others
    Hi, this is expected as an optimistic fetch is done for ISR paths on hover in case a revalidation has occurred to attempt getting fresh content before click, in most cases this will 304 with an empty response body although you have "disable cache" checked which prevents this.

    You shouldn't have to worry about resource errors from how frequently you ship, latest version of Next.js can protect against skew!

    Coming soon to Next.js: you no longer have to provide `href` and `as` for dynamic routes, only `href` will be enough 🚀 In Next.js 9.5 we made some big changes to the Next.js runtime that made this possible. This is available on next@canary if you want to try it out.
