Lua bytecode doesn't compress well (with LZMA)

[Matt Campbell <mattcampbell@...>]

I've noticed that Lua 5.1 bytecode, compiled with the -s option, doesn't 
compress as well as the equivalent Lua source code.  I have a Lua source 
tree that's about 1.4 MB uncompressed, and when I compress it with 7-Zip 
using LZMA and solid compression, the archive's file size is 183,262 
bytes.  But when I compress the equivalent bytecode, that archive's file 
size is 265,289 bytes.  For what it's worth, I'm doing the compile on an 
x86 machine, so integers are 32-bit, little-endian.  Can anyone explain 
these counter-intuitive results?  Thanks in advance.
