10000 run averages: 'Tiny LZO': Combined: 112.6642 usec Compression: 56.3321 usec Decompression: 56.3321 usec 'miniLZO': Combined: 77.6642 usec Compression: 56.3416 usec Decompression: 21.3226 usec
now the interesting bit I thought was the following root@mini:/usr/src/lzo1x-test-4# ./fulltest [test_lzo.c::compress (93)] run took 42 microseconds [test_lzo.c::decompress (127)] run took 20 microseconds root@mini:/usr/src/lzo1x-test-4# ./tinytest [test.c::compress (91)] run took 44 microseconds [test.c::decompress (117)] BUG: lzo1x_decompress has failed ( t == -6 ) [test.c::main (149)] BUG: Decompression routine failure - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
