Hi, strange. What could be the reason then? I have 2 systems available for testing. C5 and C7. C5 runs Suse 9.3 (kernel 2.6.11) which shows the difference I have posted below. C7 runs Debian etch (kernel 2.6.18 type i686). On the C7 I see no difference between openssl version d and e but speed seems to be much slower (max 292MB/s) with both versions and not going up to over 600MB/s like you posted. Any clues?
