Hi,
Attached is tester code used for testing.
(developed by Daniel Hazelton -- modified slightly to now use 'take 6'
version for 'TinyLZO')
Cheers,

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
