If I haven't done any mistake, these figures should be accurate.
The 270kb file was downloaded several times, by a pool of 15
clients. The web server used was boa, and the test program was siege
(both of them modified for gnutls).
LZO -- and a compression algorithm in general -- can be faster than null,
if there is actual compression, and the time spend in compression is a small
fragment of the time needed for the MAC and encryption. It seems that
LZO is really fast :)
