[pfSense Support] MHz myth?

2011-01-17 Thread David Burgess
I'm familiar with the hardware sizing guide, and I've done a few
benchmarks myself, but I'm wondering if a MHz is a MHz when it comes
to pf performance, or do things like IPC and cache sizes matter? What
about RAM frequencies and latency?

Putting encryption and the various pfsense packages aside, can anybody
tell me (based on theory and/or experience) what kind of comparative
routing throughput I could expect to see from say an Athlon X2, Athlon
II X2, Phenom 2, Atom D510, Pentium D, Celeron D, Core Duo, Core 2
Duo, Pentium G6950 and a Core i7, all dual-core and controlling for
NIC and core clock differences?

They are not comparable, a Geode 500Mhz is good for about 70, a 500Mhz 
PIII was good for about 250, a intel D510 is good for about 400, a C2D 
(2.13) should be able to do 600-800 depending on motherboard.


I now have Core i3 3.2Ghz firewalls, clockspeed rules, not in the 
absolute sense, but prefer clockspeed over cores. I have no idea how 
fast these go yet. It has just 6 gig ports so I really don't know what 
the fastest it can do is. It should easily do gigabit wirespeed.


If you can choose between a higher clocked dual core or a lower clocked 
quad. Take the higher clocked dual core.
