this will help There is a Windows API call FlushInstructionCache()
Perhaps this is what you need? It is typically used by self modifying code to make sure changes to code in the RAM are visible to the processor.

it helps some times __builtin_prefetch has three arguments; the third one is the cache level. AFAICT, this has only effect on SSE, where it generates prefetchnta, prefetcht1, prefetcht2, prefetcht3, respectively.

how to prefetch / cache iframe content?

I wish this help you Loading the iframe content makes the browser cache the page in it, so that if you load it a second time later, the browser will simply fetch it from cache, unless your server is set up to always load the content afresh. I suspect that if you're seeing it reload the iframe's page each time you revisit it, you either forgot to indicate how long the page should be cached for, or your server isn't set up to say "this page has not been modified since ..." so the browser doesn't try to reload the page, or the page is served with a header that indicates it cannot be cached.
(If you want to preload the content for the first run, that's the same thing as loading it in the iframe, with the iframe hidden, and then showing it when the iframe content is ready.)

Hope that helps V8 and the Linux perf tool support each other, see the documentation. If you have a very recent system (IIRC kernel >= 4.4 and perf >= 4.10), you can skip the steps for compiling your own kernel and perf.

Is there any way to prefetch or cache audio in React Native?

With these it helps With lack of information, I believe you are asking if you can download audio with react native? You can use something like https://www.npmjs.com/package/rn-fetch-blob This will allow you to save a stream to phone storage, give you a path to the file on the phone, then you can save that to reuse at a later time.
An example from their docs.
code :
// add this option that makes response data to be stored as a file,
// this is much more performant.
fileCache : true,
.fetch('GET', 'http://www.example.com/file/example.zip', {
  //some headers ..
.then((res) => {
  // the temp file path
  console.log('The file saved to ', res.path())
