With the right hardware, yes, that's what we're experiencing with latent ha= rdware that we've been tasked with benchmarking. > Works like a charm here for us. 50+ boxes running 8.x, most of which are = 8-stable. >=20 But I bet you're not sitting 88 units of Thunderbolt cards that don't work = in 8.3. 8.3 is also exhibiting major problems with the igb-based NICs on those same= 88 units. > No offence meant, but I'd take 8.3 over 9.x any day. > Any night too, for that matter. >=20 (smiles) > YMMV but PF + pfsync + carp (and some boxes with nginx or relayd on top) = is > pretty good for our workload on 8.3. I do indeed appreciate the vote of confidence. The hope is that when we get= through our mfi and igb problems that 8.3 will be a slammin' victory on th= is hardware (but until then, we're fighting the good fight). --=20 Devin _____________ The information contained in this message is proprietary and/or confidentia= l.
