PCI CPU and all that stuff story
< Scrye> pci-e > pci-x > pci 64bit > pci 32bit
< Scrye> 500mbps for pci 32, 1000 for pci64/66, 1000 full duplex for pci-x-100/133, and 2gig pcie x1, 4gig pcie-x4, 10gig pciex8 10gig full pci-x16
< Scrye> roughly
< PumpkinPie> multiple pci-e busses could do 10 mpps
< PumpkinPie> I dont understand ?
< glut> Scrye: and what about cpu that handles stuff?
< Scrye> ghz per gigabit
< Scrye> PumpkinPie : because a single pci-e x16 cant do 10mpps
< Scrye> glut : one of those new quad core xeons should beable to handle a 10 gigabit feed
* PumpkinPie shakes head
< PumpkinPie> wha
< Scrye> 10mpps is an insane amount of traffic
< PumpkinPie> my router does 119 mpps
< Scrye> your router has an asic
< PumpkinPie> foundry has some products that do 2 billion pps
< Scrye> those have ascis
< Scrye> those dont have busses per se
< Scrye> well they dont hit a main cpu
< Scrye> i almost guaruntee you wont find a software router that does >1mpps
< Scrye> the cisco 7200 is the last of the software based routers that can even do more than 500k
< Scrye> from cisco anyway
< PumpkinPie> but using multiple pci-e cards helps how ?
< Scrye> because the bus is the slowest part
< Scrye> i didnt say cards
< Scrye> i said busses
< Scrye> and youd need at least 1 cpu/core per bus
< PumpkinPie> how can you have multiple busses?
< Scrye> specially designed motherboards
< Scrye> i think some megahigh end server boards have independant buses
< PumpkinPie> pci-e is very fast
< PumpkinPie> its a quantum leap
< PumpkinPie> someone should try a intel pci-e with the napi driver
Intel Quad PCI-X NICs
< Scrye> [ 28.457515] e1000: 0000:03:00.0: e1000_probe: (PCI Express:2.5Gb/s:Width x4)
< Scrye> 00:15:17:43:b0:60
< Scrye> [ 28.552898] e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network Connection
< Scrye> thats a quad-gig pcie-x4 card
< Scrye> i bet this quad cpu box could do 1.5mpps
< edgecase> it's hard to find better than intel
< Scrye> 400$ each, well worth it
< Scrye> this box will never see .01 load heh
