I've never seen anyone posting this kind of benchmark, so here is what I found out: here the results of nbench: http://phpfi.com/71540 here is what openssl speed gives me: http://phpfi.com/71545 Sorry for posting it there, but I don't want to send attachments to this list. Please notice the memory speed penalties while the system is running on amd64 kernel. I would like to know what causes this kind of low performance when memory is being accessed. Is this a hardware problem or a problem with FreeBSD? Generally, FreeBSD-amd64 performs slightly better than FreeBSD-i386 and it's stable as expected, but I cannot find any solution to the memory problems that affect memory intensive applications as you can see.
