Is there any particular reason you need 64 bits? The only good reasons I can think of are that you need to use more than about 3GB total userspace RAM and/or a process needs to use more than about 1.5GB RAM for itself.

I'm running FreeBSD 7.0 amd64 on a few of my machines. Apart from some oddities with one brand of ethernet card (and some other documented incompatibilities which didn't affect me) it's been smooth sailing - everything works the same as the 32 bit version, except you can't share binaries between them.

Just remember, if you don't have a good reason for going 64 bit, it's not going to be a magic bullet...

Code:

66 processes:  4 running, 62 sleeping
CPU states: 86.5% user,  0.0% nice, 12.5% system,  0.2% interrupt,  0.7% idle
Mem: 3723M Active, 3475M Inact, 428M Wired, 245M Cache, 214M Buf, 35M Free
Swap: 1024M Total, 152K Used, 1024M Free

  PID USERNAME  THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU COMMAND
32674 mysql      17  44    0  6480M  3667M ucond  1 954:35 72.71% mysqld
