-The caches are stored in `$TMP/v8-compile-cache/V8_VERSION`, where there are `.BLOB` and `.MAP` files corresponding to the entry module that required `v8-compile-cache`. The cache is _entry module specific_ because it is faster to load the entire code cache into memory at once, than it is to read it from disk on a file-by-file basis.
