Nope, your storage subsystem is generally the limit once you are on GigE and as Aphasia said the bandwidth is constant.emorgoch wrote:One thing that notfred didn't mention is that there's a limited bandwidth available on the line. With TOE and fast CPUs, that's generally a bottleneck.
Not quite. 802.11 is based on the 802.3 principles but there are differences, especially in the area of jumbo frames.emorgoch wrote:I'd also quickly mention that WiFi is still Ethernet, just down with electromagnetic radiation as the signalling mechanism rather than electrons going down a wire.
Yup, used to use Ixia boxes heavily whilst I was the software developer responsible for all Cisco CRS Ethernet interfaces - 10GigE at 64bytes is over 14million packets per second. You need hardware handling to cope with that kind of throughput, to say nothing of the 100GE interface that I helped fix the demo for.Aphasia wrote:Even better is programs like chariot that we used at work that can tailor specific stream and patterns including errors to see that a network handles everything correctly. And even better than that are the nifty little dedicated boxes with 10Gbit fiber interfaces that you connect to the network that does the same thing, but just a heck of a lot more of it. That said, I watched a few people miss a tiny detail one time during such a setup and the result was, never try to enable port-mirroring on a switchport passing 10 gbits of traffic with 64 byte packets, that will make your tests go awry. On the other hand, it does does work decently with 1500byte packets.
