thats what i said there is no affect while restoration at all....
observe the dat file they are 0 kb and will be the same during whole process, precomp not uses temps during restoration at all bt precomp always make a temp file if the same exists it rename it to something else bt while recompression it constantly new temp file with every stream it finds, the version u r reffering to makes 4 temp files per stream (decompression -> recompression -> decompression -> recompression), the last 2 only used for partial matches, at same time, so think urself three precomp running at a time, total 12 temp files, there are no communication between all these precomp instances ,all wills to write the temp file with same name (default one tempfile1, tempfile2....etc) and overwrite others temp file manytimes and which led to more work for the prcomp

bt while restoration things are differrent precomp no longer checks crc and all that stuffs becaz everything is already done while recompressing part, so no need of temp files at all..... thats why u see only 1 tempfile which is of 0 kb only, precomp not even uses those at all means u can use ppx2 while restoring safely bt not when recompressing
