Hi, These are the results I reported (median of 5 plus an additional not considered first run) on the Steve Reid's SHA1 implementation using the same flags to the compiler that I used for previous tests. GCC 4.3.3: real 0m2.627s GCC 4.4.1: real 0m3.742s In both cases it showed to be slower than other implementations I have already tried. Additional note: as for gnulib SHA1, GCC 4.4.1 produced slower code than GCC 4.3.3. Cheers, Giuseppe Steven Noonan <steven@xxxxxxxxxxxxxx> writes: > > Interesting.
