The problem is not just the decompresser size itself, but how much memory it uses. LZO is pretty special (though not unique) in that its requisites in that area are very low; as low as just the source and destination buffers. With LZMA (and other algorithms) we would need intermediate buffers and other memory-consuming things like dictionaries and such. I'm neither a compression expert nor an assembly guru, but the tradeoff might not be up to the task. --=-affn5FFfwjagA+Jixk7C Content-Type: application/pgp-signature; name=signature.asc Content-Description: Esta parte del mensaje =?ISO-8859-1?Q?est=E1?= firmada digitalmente -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUASFcl1KSl+Fbdeo72AQIJfA/8CzAzXDFFy9aKc9QoGZDfh3O+HGH/dc4i RHbxd5FAfq7/yom2Sy/OvLmUqMYCg+5xiNEhvW/9SaBfDLmMNGMPWech4E4rl9m4 7Okl9ZuHLTRvQwZ1JgFrpnXpfL/mvDYLFBiUQKTHdsrEFoV+gvxoiD4oNLnkVuG7 nQGT0s1lHVIvETDcMjO0FCpD9uXAJ/Irk++JsBhwuUNDuXuT/yXhBbolXcT2PJ7Q Y0ed0m/qym867Jz6pUm9/vG/AF7d35ZqgNv+GiHro/Cj6f1cmgCEDkon5up/x3Gs UyVShd8Z9NoLBAFmr0c40GpKVmcQtxGwJvoo8U95NTZRgknEG3pd6R5zp5AYyNWQ Oq6mEtoZNPMKkhxOr4VNGVkiAux+pvsiIOHoY+FLICOto45jrRSh0t60NsR/Yq8k lsTERfrPVSc4187iS4zz1Oe1fCTXdUhErBcrdGifoMEohb4i7Qw/VMVdqkUTjSzq FF/CZEcAiSIDc3Ah7fT0op0TK2WeAKwzg3LDTkUgY7Xktydn6BYWEeRgcqImecA7 S5mmPas/Xuzw9k3kG1nG9F3+E0MObMU74GCgz3VS8Vxyi/SCfDh7mue+5nMVUzMX sdCo2gtVbKoAlXSEFvt420jd0NSnosWINzB7n7fumcR58CFfPwmZYOYwgJSPYzp+ SXGRjwCCTpk= =se00 -----END PGP SIGNATURE----- --=-affn5FFfwjagA+Jixk7C--
