Here is another way,
with "list" as the file with list of filenames
split the list file into n chunks .. list_1, list_2 ... list_n
you should arrive at a bench mark say 10 to 50 or something like that
now operate any of the logic on the n list_* files simulatenously
and this should definitely be faster as mv is executed in multiples.

LUAC(1) General Commands Manual LUAC(1)
NAME
luac - Lua compiler
SYNOPSIS
luac [ options ] [ filenames ]
DESCRIPTION
luac is the Lua compiler. It translates programs written in the Lua programming language into binary files that can be later loaded and
executed.
The main advantages of precompiling chunks are: faster loading, protecting source code from accidental user changes, and off-line syntax
checking.
Pre-compiling does not imply faster execution because in Lua chunks are always compiled into bytecodes before being executed. luac simply
allows those bytecodes to be saved in a file for later execution.
Pre-compiled chunks are not necessarily smaller than the corresponding source. The main goal in pre-compiling is faster loading.
The binary files created by luac are portable only among architectures with the same word size and byte order.
luac produces a single output file containing the bytecodes for all source files given. By default, the output file is named luac.out, but
you can change this with the -o option.
In the command line, you can mix text files containing Lua source and binary files containing precompiled chunks. This is useful to com-
bine several precompiled chunks, even from different (but compatible) platforms, into a single precompiled chunk.
You can use '-' to indicate the standard input as a source file and '--' to signal the end of options (that is, all remaining arguments
will be treated as files even if they start with '-').
The internal format of the binary files produced by luac is likely to change when a new version of Lua is released. So, save the source
files of all Lua programs that you precompile.
OPTIONS
Options must be separate.
-l produce a listing of the compiled bytecode for Lua's virtual machine. Listing bytecodes is useful to learn about Lua's virtual
machine. If no files are given, then luac loads luac.out and lists its contents.
-o file
output to file, instead of the default luac.out. (You can use '-' for standard output, but not on platforms that open standard out-
put in text mode.) The output file may be a source file because all files are loaded before the output file is written. Be careful
not to overwrite precious files.
-p load files but do not generate any output file. Used mainly for syntax checking and for testing precompiled chunks: corrupted files
will probably generate errors when loaded. Lua always performs a thorough integrity test on precompiled chunks. Bytecode that
passes this test is completely safe, in the sense that it will not break the interpreter. However, there is no guarantee that such
code does anything sensible. (None can be given, because the halting problem is unsolvable.) If no files are given, then luac
loads luac.out and tests its contents. No messages are displayed if the file passes the integrity test.
-s strip debug information before writing the output file. This saves some space in very large chunks, but if errors occur when run-
ning a stripped chunk, then the error messages may not contain the full information they usually do. For instance, line numbers and
names of local variables are lost.
-v show version information.
