Three ways a small file could still make a redaction run long or large: - direct_parms kept /JBIG2Globals as given, so a direct array there was copied for each entry (427 MiB from 32 KB). It is kept only when it is a reference, as Document::with_direct_parms keeps it; a direct value is no stream, so no decoder reads it. - The entries copied were bounded only by /Filter's length, and the work repeated for every stream that uses a dictionary: time grew with the square of the file (117 s from 249 KB). A /Filter longer than any decoder takes (MAX_CHAIN, and a /Crypt) is read as no filter, so its parameters aren't read either; no decoder reads such a stream anyway. - named() read every entry of every stream's parameters, through up to 33 references each, with nothing shared between streams. Names keeps what each value the file refers to names, for the whole run, so streams sharing an array or an entry cost it once; unshare adds a shared list, and finds what it matches, once too.
