    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
